Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical instruments, and in particular to a surgical clip continuous hair ligation forceps. Background Art
[0002] Many surgical procedures require ligation of blood vessels or other body fluid tubes or tissue ducts (such as veins and arteries in the human body) during the operation. For example, many surgical procedures require cutting off blood vessels and may require ligation of these blood vessels to reduce the amount of blood left at the surgical site. In addition, in some cases, the surgeon may wish to permanently ligate the blood vessels. At this time, the blood vessels or other tissues can be ligated by using ligation clamps or surgical sutures. The use of surgical sutures requires complex manipulation of needles and suture materials to form the knots required to tighten the blood vessels. Especially in endoscopic surgery characterized by limited space and visibility, this complex operation is time-consuming and difficult to complete. In contrast, the use of ligation clamps is relatively easy and quick. Therefore, the use of ligation clamps in endoscopic surgery and open surgery has increased significantly.
[0003] The ligation forceps currently on the market use the forceps head to clamp the external surgical clip and then clamp the surgical clip on the blood vessel and other tissues. This method requires repeated clamping of the external surgical clip, and it is easy to deviate when clamping. Therefore, there are designs on the market that can insert surgical clips into ligation forceps. Although this method can accommodate multiple surgical clips at one time and push the surgical clips to the forceps head accordingly, the surgical clips are easy to get stuck in the ligation forceps, resulting in the problem that they cannot be pushed out. The surgical clips are also easy to fly out when pushed out and fall into the patient's body, causing safety hazards and hindering the operation. Summary of the invention
[0004] In view of the above-mentioned shortcomings, the purpose of the present invention is to provide a surgical clip continuous ligation forceps, which can accommodate multiple surgical clips and push them out accurately and stably to prevent them from falling, thereby effectively improving the safety of the operation. The activation design of the handle is conducive to the user's control of the pushing situation, which is beneficial to the operation.
[0005] The technical solution adopted by the present invention to achieve the above-mentioned purpose is:
[0006] The clamp is arranged in sequence and placed in the clamp magazine rod, and also includes an outer sleeve sleeved outside the clamp magazine rod, and a push-clamp spring sheet slidably arranged on the clamp magazine rod. A transverse column is formed on one end of the surgical clip, and a plurality of push-out spring sheets are formed on the push-clamp spring sheet and extend obliquely toward the front end of the inner wall of the clamp magazine rod, and a push-out limit opening is formed on the front end of the push-out spring sheet and presses the transverse column to limit the position. The clamp magazine rod is formed with a plurality of anti-recoil spring sheets and extend obliquely toward the front end of the inner wall of the push-clamp spring sheet, and an anti-recoil limit opening is formed on the front end of the anti-recoil spring sheet and presses the transverse column to limit the position.
[0007] As a further improvement of the present invention, at least one first anti-flying bullet sheet is formed on one side of the clamp rod near one end of the clamp head and near the push-clamp spring sheet, and the sheet is obliquely bent and extended toward the inside of the clamp rod and one end of the clamp head. At least one second anti-flying bullet sheet is formed on the other side of the clamp rod near one end of the clamp head, and the sheet is bent into the inside of the clamp rod and extends toward the jaw end of the clamp head.

[0009] As a further improvement of the present invention, it also includes an anti-deflection spring sheet arranged on one of the outer walls of the clamping rod and hinged to the clamp head, the clamp head including an upper clamp head rotatably arranged on one of the outer walls of the clamping rod, and a lower clamp head rotatably arranged on the outer wall of the clamping rod and arranged opposite to the upper clamp head, the anti-deflection spring sheet includes an anti-deflection main body spring sheet arranged on the outer wall of the clamping rod, an upper anti-deflection limiting spring sheet formed on the anti-deflection main body spring sheet and extending toward the clamp head direction and connected to the upper clamp head, and a lower anti-deflection limiting spring sheet formed on the anti-deflection main body spring sheet and extending toward the clamp head direction and connected to the lower clamp head, the upper anti-deflection limiting spring sheet and the lower anti-deflection limiting spring sheet gather together when no external force is applied.
[0010] As a further improvement of the present invention, the upper anti-bias limiting spring sheet is formed with an upper anti-bias pressing sheet bent upward to press the upper clamp head to limit the position at one end near the upper clamp head; the lower anti-bias limiting spring sheet is formed with a lower anti-bias pressing sheet bent downward to press the lower clamp head to limit the position at one end near the lower clamp head; an upper clamp limiting sheet extending horizontally toward the handle direction is formed on one side of the upper clamp head, and the upper anti-bias pressing sheet is pressed against the upper clamp limiting sheet; a lower clamp limiting sheet extending horizontally toward the handle direction is formed on one side of the lower clamp head, and the lower anti-bias pressing sheet is pressed against the lower clamp limiting sheet.
[0011] As a further improvement of the present invention, an excitation block is formed in the fixed handle, which is generally arc-shaped and on the rotation trajectory of the handle. The excitation block is formed with a plurality of excitation steps at one end facing the handle. An excitation activity plate is formed on the handle and extends horizontally toward the rear. An excitation activity step extends laterally from the tail end of the excitation activity plate. The excitation activity plate has no contact with the excitation block, and the excitation activity step slides on a plurality of excitation steps.
[0012] As a further improvement of the present invention, the end of the excitation block facing the handle is further formed with a confirmation step located at the upper end of the excitation step, and a reset step located at the end of the excitation block away from the excitation step.
[0013] As a further improvement of the present invention, it includes an upper support member arranged between one of the outer walls of the clamping rod and the outer sleeve, and at least one rib is formed on the inner wall of the upper support member facing the clamping rod, which extends radially as a whole and faces the clamping rod, and the rib is semicircular as a whole.
[0014] As a further improvement of the present invention, it also includes a support bar arranged in the push-pull rod and pushing the push-clamp spring sheet, and the upper and lower ends of the support bar are formed with a plurality of protrusions arranged in sequence and protruding toward the inner wall of the clamping rod.
[0015] As a further improvement of the present invention, the diameter of the outer sleeve is 9 mm to 10 mm.
[0016] The beneficial effects of the present invention are:
[0017] The surgical clip continuous ligation forceps are configured to include a fixed handle, a handle rotatably arranged on the fixed handle, a push-pull rod arranged in the fixed handle and pushed by the handle, a clamping magazine rod pushed by the push-pull rod, and a clamp head arranged on an end of the clamping magazine rod away from the handle, the surgical clips are arranged in sequence and placed in the clamping magazine rod, and also include an outer sleeve sleeved on the outside of the clamping magazine rod, a pushing clamp spring sheet slidably arranged on the clamping magazine rod, a transverse column is formed on one end of the surgical clip, and a plurality of push-out spring sheets are formed on the pushing clamp spring sheet and extend obliquely toward the front end of the inner wall of the clamping magazine rod, and a push-out limit opening is formed on the front end of the pushing clamp spring sheet and presses the transverse column to limit the position, and a plurality of anti-recoil spring sheets are formed on the clamping magazine rod and extend obliquely toward the front end of the inner wall of the pushing clamp spring sheet, and an anti-recoil limit opening is formed on the front end of the anti-recoil spring sheet and presses the transverse column to limit the position.
[0018] The clamp magazine rod is fixed on the fixed handle, and one end of the transverse column on each set of surgical clamps is pressed against the anti-backward limit opening of the corresponding anti-backward spring sheet. Due to the semi-arc-shaped structure of the anti-backward limit opening, the surgical clamps can be effectively prevented from retreating during the pushing process, which is conducive to the precise pushing out of the surgical clamps.
[0019] When the surgical clip needs to be tightened on a blood vessel or other tissue, the user presses the handle, and the handle pushes the push-pull rod, which drives the outer sleeve to move forward and drives the push-clip spring to move forward on the clamp magazine rod, and the push-out limit opening in the push-out spring on the push-clip spring is pressed against the other end of the transverse column of a group of surgical clips, and the other end of the transverse column of the surgical clip is pressed by the push-out limit opening, so that the push-clip spring pushes the surgical clip to the anti-retraction limit opening of the anti-retraction spring of the previous group. Because the push-out limit opening is semi-arc-shaped, the surgical clip cannot retreat when pushed by the push-out spring, thereby completing the purpose of moving the surgical clip forward by one group. At the same time, the surgical clip of the first group is pushed onto the clamp head, and the outer sleeve is driven forward by the push-pull rod to move forward so that the inner wall of the front end of the outer sleeve is pressed against the opened clamp head, so that the clamp head is retracted, thereby closing the surgical clip in the clamp head, and the surgical clip is tightened on the blood vessel or other tissue. The whole process is easy to use, and multiple surgical clips can be effectively and accurately pushed onto the clamp head in sequence and tightened accordingly on blood vessels and other tissues, avoiding the need to repeatedly clamp the surgical clips, saving surgical time, improving surgical efficiency, preventing them from falling, and effectively improving surgical safety.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0073] Please refer to Figures 1 to 32 The embodiment of the present invention provides a surgical clip 06 continuous ligation forceps, comprising a fixed handle 01, a handle 02 rotatably arranged on the fixed handle 01, a push-pull rod 03 arranged in the fixed handle 01 and pushed by the handle 02, a clamping magazine rod 04 pushed by the push-pull rod 03, and a clamp head 05 arranged on the end of the clamping magazine rod 04 away from the handle 02. The surgical clips 06 are arranged in sequence and placed in the clamping magazine rod 04, and also include an outer sleeve 07 sleeved on the outside of the clamping magazine rod 04, and a push-clip spring 08 slidably arranged on the clamping magazine rod 04. The surgical clips 06 A horizontal column 061 is formed on one end, and the push-clamp spring piece 08 is formed with a plurality of ejection spring pieces 081 which extend obliquely toward the front end of the inner wall of the clamping rod 04, and the front end of the ejection spring piece 081 is formed with an ejection limit opening 0811 which is semi-arc-shaped as a whole and presses the horizontal column 061 to limit the position, and the clamping rod 04 is formed with a plurality of anti-backward spring pieces 041 which extend obliquely toward the front end of the inner wall of the push-clamp spring piece 08, and the front end of the anti-backward spring piece 041 is formed with an anti-backward limit opening 0411 which is semi-arc-shaped as a whole and presses the horizontal column 061 to limit the position.
[0074] The clamping magazine rod 04 is fixed on the fixed handle 01, and one end of the transverse column 061 on each group of surgical clamps 06 is pressed against the anti-backward limit opening 0411 of the corresponding anti-backward spring sheet 041. Due to the semi-arc-shaped structure of the anti-backward limit opening 0411, the surgical clamp 06 is effectively prevented from retreating during the pushing process, which is conducive to the precise pushing out of the surgical clamp 06.
[0075] When the surgical clip 06 needs to be fastened to the blood vessel or other tissue, the user presses the handle 02, and the handle 02 pushes the push-pull rod 03, and the push-pull rod 03 drives the outer sleeve 07 to move forward and drives the push-clip spring piece 08 to move forward on the clamping magazine rod 04, and the push-out limit opening 0811 in the push-out spring piece 081 on the push-clip spring piece 08 presses against the other end of the transverse column 061 of a group of surgical clips 06, and the other end of the transverse column 061 of the surgical clip 06 is pressed by the push-out limit opening 0811, so that the push-clip spring piece 08 pushes the surgical clip 06 to the anti-backward spring piece of the previous group. On the anti-retraction limit opening 0411 of 041, because of the semi-arc structure setting of the push-out limit opening 0811, the surgical clip 06 cannot retreat when being pushed by the push-out spring piece 081, thereby completing the purpose of moving the surgical clip 06 forward by one group. At the same time, the surgical clip 06 of the first group is pushed onto the clamp head 05, and the outer sleeve 07 is driven by the push-pull rod 03 to move forward so that the inner wall of the front end of the outer sleeve 07 is pressed against the opened clamp head 05, and the clamp head 05 is closed, so that the surgical clip 06 in the clamp head 05 is closed, so that the surgical clip 06 is fastened to the blood vessel and other tissues. The whole process is convenient to use, and multiple surgical clips 06 are effectively and accurately pushed out of the clamp head 05 in sequence, and are fastened to the blood vessel and other tissues accordingly, avoiding the need to repeatedly clamp the surgical clip 06, saving the time of the operation, improving the efficiency of the operation, preventing it from falling, and effectively improving the safety of the operation.
[0076] Preferably, Figures 7 to 11 As shown, in order to prevent the push-clamp spring piece 08 from excessively moving on the clamping magazine rod 04, a plurality of travel limit grooves 047 are arranged on the side wall of the clamping magazine rod 04, and a plurality of travel limit blocks 082 movable in the travel limit grooves 047 are formed on the push-clamp spring piece 08. The length of the travel limit groove 047 is the distance that each surgical clip 06 needs to be pushed forward, so that each time the push-clamp spring piece 08 is driven to slide, it can just push a group of surgical clips 06 forward, thereby preventing the problem of excessive movement of the push-clamp spring piece 08.
[0077] In order to let the user know that the surgical clip 06 in the clip magazine rod 04 has been used up, Fig.15As shown, the last surgical clip 06 in the clamp rod 04 is configured as a warning clip with a different structure. When the warning clip is pushed out, the user can know that the surgical clip 06 in the clamp rod 04 has been used up and the clamp rod 04 needs to be replaced, which is beneficial for the user to control the surgical clip 06 continuous ligation forceps.
[0078] For the specific use of this surgical clip 06 continuous ligation forceps, such as Figures 1 to 4 As shown, in the first step, the user pushes the handle 02, and the surgical clip 06 is pushed out from the clamp magazine rod 04 to the clamp head 05, and the outer sleeve 07 moves forward slightly to press the clamp head 05 to close it, so that the clamp head 05 is slightly tightened, thereby preventing the surgical clip 06 from flying out of the clamp head 05. In the second step, the user continues to push the handle 02, and the outer sleeve 07 continues to move forward to the end to completely tighten the clamp head 05, so that the surgical clip 06 is closed and tightly tied to the blood vessels and other tissues. In the third step, the user continues to push the handle 02, and the outer sleeve 07 cannot move forward any further, and the handle 02 rotates to the end. In the fourth step, the handle 02 is released and the handle 02 is reset.
[0079] In order to prevent the surgical clip 06 from flying out of the forceps head 05 when being pushed out, Figures 9 to 14 As shown, at least one first anti-flying shrapnel 042 is formed on one side of the clamp rod 04 near one end of the clamp head 05 and near one side of the clamp push shrapnel 08, and is bent and extended obliquely toward the inside of the clamp rod 04 and one end of the clamp head 05. At least one second anti-flying shrapnel 043 is formed on the other side of the clamp rod 04 near one end of the clamp head 05, and is bent and extended toward one end of the jaws of the clamp head 05. When the user presses the handle 02 to push out the surgical clip 06 in the clamp rod 04, the surgical clip 06 is symmetrically clamped and limited by the first anti-flying shrapnel 042 and the second anti-flying shrapnel 043 at the front end of the clamp rod 04, thereby buffering the impact of the clamp rod 04 on the surgical clip 06, effectively preventing the surgical clip 06 from flying out of the jaws of the clamp head 05 and falling into the patient's body due to excessive thrust when being pushed out, thereby ensuring the safety of the operation. By setting the first anti-flying shrapnel 042 as a structure that bends into the clamping magazine rod 04 and then extends toward one end of the jaws of the clamp head 05, and setting the second anti-flying shrapnel 043 as a structure that bends into the clamping magazine rod 04 and then extends toward one end of the jaws of the clamp head 05, the first anti-flying shrapnel 042 and the second anti-flying shrapnel 043 as a whole form a triangular shape extending into the clamping magazine rod 04, so that the surgical clip 06 is pushed to the jaws of the clamp head 05 in the clamping magazine rod 04. The blocking force of the first anti-flying shrapnel 042 and the second anti-flying shrapnel 043 is increasingly greater, and the surgical clip 06 is stabilized at the jaws of the clamp head 05, thereby achieving the purpose of buffering the forward impact force on the surgical clip 06, effectively preventing the surgical clip 06 from flying out of the jaws of the clamp head 05 and falling into the patient's body, thereby improving the safety of the operation.
[0080] Regarding the specific structural setting of the first anti-flying shrapnel 042, as shown in FIG. Figures 9 and 10 As shown, the first anti-flying shrapnel 042 includes a first anti-flying connecting piece 0421 connected to one side of the clamping bar 04 near one end of the clamp head 05 and extending horizontally toward the jaws of the clamp head 05, a first anti-flying inclined piece 0422 connected to one end of the first anti-flying connecting piece 0421 toward the jaws of the clamp head 05 and extending obliquely toward the inside of the clamping bar 04 and the jaws of the clamp head 05, and a first anti-flying extending piece 0423 connected to one end of the first anti-flying inclined piece 0422 toward the jaws of the clamp head 05 and extending horizontally toward the jaws of the clamp head 05. The first anti-flying connecting piece 0421 is used to connect the first anti-flying shrapnel 042 with the clamping bar 04. Its horizontal structure ensures connection and is easy to stamp, thereby improving production efficiency. By setting the first anti-flying inclined piece 0422 as a structure that extends obliquely toward the inside of the clamp rod 04 and the jaws of the clamp head 05, the blocking force on the inclined surface of the surgical clamp 06 pushed from the clamp rod 04 is gradually increased until it is relatively stagnant and limited on the first anti-flying extension piece 0423, thereby effectively preventing the surgical clamp 06 from flying out of the jaws of the clamp head 05 and falling into the patient's body due to excessive thrust when being pushed out, thereby ensuring the safety of the operation. By setting the first anti-flying extension piece 0423 as a structure extending horizontally toward the jaws of the forceps head 05, when the surgical clip 06 is pushed to the first anti-flying extension piece 0423, its side is pressed against the first anti-flying extension piece 0423 and is buffered by the first anti-flying extension piece 0423. However, it will not be unable to be pushed to the jaws of the forceps head 05 due to the increasing blocking force under the tilting effect of the first anti-flying inclined piece 0422, thereby ensuring that the surgical clip 06 will not fly off and the normal operation of the transportation is guaranteed.
[0081] Preferably, Figures 9 and 10 As shown, the number of the first anti-flying shrapnel pieces 042 is three groups, and the three groups are evenly arranged on the tube wall of one side of the clamping magazine rod 04, so that the blocking force on one side of the surgical clamp 06 is uniform, preventing the surgical clamp 06 from shifting, and improving the accuracy of the ligation forceps in clamping the blood vessel.
[0082] Regarding the specific structural setting of the second anti-flying shrapnel 043, as shown in FIG. Figure 12 to Figure 13As shown, the second anti-flying shrapnel 043 includes a second anti-flying inclined sheet 0431 connected to the other side of the clamp rod 04 near one end of the clamp head 05 and extending obliquely toward the inside of the clamp rod 04 and the jaws of the clamp head 05, and a second anti-flying extension sheet 0432 connected to one end of the second anti-flying inclined sheet 0431 facing the jaws of the clamp head 05 and extending horizontally toward the jaws of the clamp head 05. By setting the second anti-flying inclined sheet 0431 to be a structure that extends obliquely toward the inside of the clamp rod 04 and the jaws of the clamp head 05, the blocking force on the inclined surface of the surgical clip 06 pushed from the clamp rod 04 is gradually increased, and the first anti-flying inclined sheet 0422 is cooperated to make the surgical clip 06 relatively stagnant and limited between the first anti-flying extension sheet 0423 and the second anti-flying extension sheet 0432, effectively preventing the surgical clip 06 from flying out of the jaws of the clamp head 05 and falling into the patient's body due to excessive thrust when being pushed out, thereby ensuring the safety of the operation. By setting the second anti-flying extension piece 0432 as a structure extending horizontally toward the jaws of the forceps head 05, when the surgical clip 06 is pushed out to the second anti-flying extension piece 0432, its side is pressed against the second anti-flying extension piece 0432 and is buffered by the second anti-flying extension piece 0432, but it will not be subject to increasing resistance force due to the inclination of the second anti-flying inclined piece 0431, resulting in the inability to be pushed to the jaws of the forceps head 05 subsequently. This ensures that the surgical clip 06 will not fly off and also ensures the normal operation of transportation.
[0083] In order to prevent the surgical clip 06 from deviating when being pushed out, resulting in inaccurate tissue such as tightening the blood vessels, such as Figure 6 , Figures 9 to 13 As shown, the front end of the clamp rod 04 is in the shape of a hollow rectangle as a whole, and the pushing clamp spring piece 08 slides in the middle and rear section of the clamp rod 04. When it is installed in the clamp rod 04, the two are combined to form a hollow rectangle as a whole, and the surgical clamp 06 is inserted between the two. The four tube wall outer sides of the clamp rod 04 facing the jaws of the clamp head 05 are arranged in sequence with anti-deflection guide blocks 045 that protrude outward and retract inward. The surgical clamp 06 is inserted into the clamp rod 04 and pushed toward the clamp head 05, and when pushed to the clamp head 05, it first contacts the anti-deflection guide block 045, and returns to the middle part of the clamp head 05 under the retracted and inclined guiding action of the anti-deflection guide block 045, thereby effectively preventing the surgical clamp 06 from shifting and offsetting when being pushed out, resulting in inaccurate blood vessel clamping, thereby improving the safety of the operation.
[0084] Preferably, the specific structural setting of the anti-deflection guide block 045 is as follows: Figure 6 , Figures 9 to 13As shown, the two groups of anti-deflection guide blocks 045 symmetrically arranged on the upper tube wall and the lower tube wall of the clamp magazine rod 04 are in the shape of a rectangular block as a whole, and the rectangular block structure matches the overall long and flat structure of the surgical clip 06, so that the two groups of anti-deflection guide blocks 045 on the upper tube wall and the lower tube wall can better guide the surgical clip 06 to the center and prevent the surgical clip 06 from deviating when it is pushed out for use.
[0085] Preferably, Figure 6 , Figures 9 to 13 As shown, the two groups of anti-deviation guide blocks 045 symmetrically arranged on the left tube wall and the right tube wall of the clamp magazine rod 04 are in a triangular shape as a whole, and the triangular shape matches the overall elongated flat structure of the surgical clip 06, so that the two groups of anti-deviation guide blocks 045 on the left tube wall and the right tube wall can better guide the surgical clip 06 to the center and prevent the surgical clip 06 from shifting during the process of being pushed out and used. The triangular shape not only achieves guidance but also saves production costs.
[0086] Preferably, Figures 9 to 16 As shown, in order to further prevent the surgical clip 06 from retreating due to factors such as blocking force when being pushed out of the clamp magazine rod 04, a downwardly bent anti-retreat hook 046 is formed on the upper tube wall of the clamp magazine rod 04, and the height of the lowest position of the anti-retreat hook 046 is lower than the height of the highest position of the upper clamp arm of the surgical clip 06 in the clamp magazine rod 04, so that the anti-retreat hook 046 is against the back side of the upper clamp arm of the surgical clip 06, and the purpose of pressing the upper clamp arm of the surgical clip 06 is to further prevent the surgical clip 06 from retreating due to factors such as blocking force when being pushed out of the clamp magazine rod 04.
[0087] In order to prevent the forceps head 05 from being offset during use, causing the surgical clip 06 to be pushed out and tied to the blood vessels and other tissues without precision, such as Figure 5 and Fig.17As shown, the surgical clip continuous ligation forceps also includes an anti-deflection spring sheet 044 arranged on one of the outer walls of the clamping chamber rod 04 and connected to the clamp head 05, the clamp head 05 includes an upper clamp head 051 rotatably arranged on one of the outer walls of the clamping chamber rod 04, and a lower clamp head 052 rotatably arranged on the outer wall of the clamping chamber rod 04 and arranged opposite to the upper clamp head 051, the anti-deflection spring sheet 044 includes an anti-deflection spring sheet 044 arranged on the outer wall of the clamping chamber rod 04 A main body spring piece 0441, an upper anti-bias limiting spring piece 0442 formed on the anti-bias main body spring piece 0441 and extending toward the clamp head 05 and connected to the upper clamp head 051, and a lower anti-bias limiting spring piece 0443 formed on the anti-bias main body spring piece 0441 and extending toward the clamp head 05 and connected to the lower clamp head 052, the upper anti-bias limiting spring piece 0442 and the lower anti-bias limiting spring piece 0443 gather together when no external force is applied. In the process of the clamping rod 04 driving the upper clamp head 051 and the lower clamp head 052 to gather together, the tail end of the upper clamp head 051 tilts upward to push the upper anti-bias limiting spring piece 0442 pressed on the tail end of the upper clamp head 051 upward, and the tail end of the lower clamp head 052 tilts downward to push the lower anti-bias limiting spring piece 0443 pressed on the tail end of the lower clamp head 052 downward, and the upper anti-bias limiting spring piece 0442 and the lower anti-bias limiting spring piece 0443 provide the The forceps head 05 has a reaction force of opening, so that the forceps head 05 can have a certain buffer force during the gathering process, thereby preventing the problem of inability to accurately ligate the blood vessel due to the too fast gathering speed, and the closing and opening stroke of the forceps head 05 is limited by the distance between the upper anti-deflection limit spring piece 0442 and the upper end of the clamping magazine rod 04, and the lower anti-deflection limit spring piece 0443 and the lower end of the clamping magazine rod 04, thereby limiting the closing and opening stroke of the forceps head 05 and preventing the problem of excessive opening of the forceps head 05. The upper anti-bias limiting spring sheet 0442 is connected to the upper clamp head 051, and the lower anti-bias limiting spring sheet 0443 is connected to the lower clamp head 052, so that the upper clamp head 051 and the lower clamp head 052 are limited in the left and right directions and the up and down directions, preventing the clamp head 05 from shifting during the operation, resulting in a large position error of the surgical clip 06 therein when tightening the blood vessel, thereby effectively improving the ligation accuracy of the ligation forceps and improving the safety of the operation.
[0088] The specific method of limiting the upper clamp head 051 by the upper anti-bias limiting spring piece 0442 is as follows: Figure 5 and Fig.17As shown, one end of the upper anti-bias limiting spring sheet 0442 close to the upper clamp head 051 is formed with an upper anti-bias pressing sheet 04421 which is bent upward to press the upper clamp head 051 to limit the position. The bent structure makes it easier for the upper clamp head 051 to drive and open the upper anti-bias pressing sheet 04421 when closing. The upper anti-bias pressing sheet 04421 can also more easily use its own elastic restoring force as a buffering reaction force to buffer the gathering force of the upper clamp head 051, thereby This prevents the problem of inability to accurately ligate the blood vessel due to excessive gathering speed, and the bent structure makes the connection between the upper anti-bias pressing plate 04421 and the upper clamp head 051 tighter and stronger, so that the upper anti-bias limiting spring sheet 0442 can effectively limit the upper clamp head 051 in the left and right directions and the up and down directions, preventing the clamp head 05 from shifting during the operation, resulting in a large position error of the surgical clip 06 therein when tying the blood vessel, effectively improving the ligation accuracy of the ligation forceps and improving the safety of the operation.
[0089] The specific method of limiting the lower clamp head 052 by the lower anti-bias limiting spring piece 0443 is as follows: Figure 5 and Fig.17 As shown, one end of the lower anti-bias limiting spring piece 0443 close to the lower clamp head 052 is formed with a lower anti-bias pressing piece 04431 which is bent downward to press the lower clamp head 052 to limit the position. The bent structure makes it easier for the lower clamp head 052 to drive and open the lower anti-bias pressing piece 04431 when closing. The lower anti-bias pressing piece 04431 can also more easily use its own elastic restoring force as a buffering reaction force to buffer the gathering force of the lower clamp head 052, thereby This prevents the problem of inability to accurately ligate the blood vessel due to excessive gathering speed, and the bent structure makes the connection between the lower anti-bias pressing plate 04431 and the lower clamp head 052 tighter and stronger, so that the lower anti-bias limiting spring sheet 0443 can effectively limit the lower clamp head 052 in the left and right directions and the up and down directions, preventing the clamp head 05 from deviating during the operation, resulting in a large position error of the surgical clip 06 therein when tying the blood vessel, effectively improving the ligation accuracy of the ligation forceps and improving the safety of the operation.
[0090] The specific method of limiting the travel of the upper clamp head 051 by the upper anti-bias limit spring piece 0442 is as follows: Figure 5 and Fig.17As shown, an upper inclined yielding surface is formed on the upper end surface of the upper anti-deflection limiting spring piece 0442, which is obliquely extended from the anti-deflection main body spring piece 0441 to the lower clamp head 052 as a whole. By setting the upper inclined yielding surface as a structural setting that is obliquely extended from the anti-deflection main body spring piece 0441 to the lower clamp head 052 as a whole, the upper inclined yielding surface of the upper anti-deflection limiting spring piece 0442 is pressed against the inner wall of the outer sleeve 07 when it is stretched open by the upper clamp head 051, and its shape is more in line with the rotating structural setting, so that the upper anti-deflection limiting spring piece 0442 is more conducive to being stretched open and limiting the upper clamp head 051, effectively avoiding the problem that the long strip shape will get stuck in other parts during rotation and is not conducive to cooperation, thereby improving the working accuracy of the anti-deflection structure of the clamp head 05 of the continuous ligation forceps.
[0091] The specific method of limiting the travel of the lower clamp head 052 by the lower anti-bias limit spring piece 0443 is as follows: Figure 5 and Fig.17 As shown, a lower inclined yielding surface is formed on the upper end surface of the lower side anti-deflection limiting spring piece 0443, which is obliquely extended from the anti-deflection main body spring piece 0441 toward the upper side clamp head 051. By setting the lower side inclined yielding surface as a structural setting that is obliquely extended from the anti-deflection main body spring piece 0441 toward the upper side clamp head 051 as a whole, the lower side inclined yielding surface of the lower side anti-deflection limiting spring piece 0443 is pressed against the inner wall of the outer sleeve 07 when it is stretched open by the lower side clamp head 052, and its shape is more in line with the rotating structural setting, so that the lower side anti-deflection limiting spring piece 0443 is more conducive to being stretched open and limiting the lower side clamp head 052, effectively avoiding the problem that the long strip shape will get stuck in other parts during rotation and is not conducive to cooperation, thereby improving the working accuracy of the anti-deflection structure of the clamp head 05 of the continuous ligation forceps.
[0092] Regarding the connection method between the upper clamp head 051 and the upper anti-deflection limiting spring piece 0442, as shown in FIG. Figure 5 and Fig.17 As shown, one side of the upper clamp head 051 is formed with an upper clamp limiting piece 0511 extending horizontally toward the handle 02, and the upper anti-bias pressing piece 04421 is pressed against the upper clamp limiting piece 0511. By setting the upper clamp limiting piece 0511 as a structure extending horizontally toward the handle 02, the upper clamp limiting piece 0511 is pressed and limited from the upper end by the upper anti-bias pressing piece 04421, and the upper clamp head 051, which is an inclined and bent structure as a whole, is extended and driven by the upper clamp head 051, which is beneficial for the upper anti-bias pressing piece 04421 to limit the stroke of the upper clamp head 051 as well as the left and right directions and the up and down directions, so as to prevent the clamp head 05 from deviating during the operation, resulting in a large position error of the surgical clip 06 therein when tightening the blood vessel, thereby effectively improving the ligation accuracy of the ligation forceps and improving the safety of the operation.
[0093] Regarding the connection method between the lower clamp head 052 and the lower anti-deflection limiting spring piece 0443, as shown in FIG. Figure 5 and Fig.17 As shown, one side of the lower clamp head 052 is formed with a lower clamp limiting piece 0521 extending horizontally toward the handle 02, and the lower anti-bias pressing piece 04431 is pressed against the lower clamp limiting piece 0521. By setting the lower clamp limiting piece 0521 as a structure extending horizontally toward the handle 02, the lower clamp limiting piece 0521 is pressed and limited from the lower end by the lower anti-bias pressing piece 04431, and the lower clamp head 052 with an inclined bending structure as a whole is extended and driven by the lower clamp head 052, which is beneficial for the lower anti-bias pressing piece 04431 to limit the travel of the lower clamp head 052 as well as the left and right directions and the up and down directions, so as to prevent the clamp head 05 from deviating during the operation, resulting in a large position error of the surgical clip 06 therein when tightening the blood vessel, thereby effectively improving the ligation accuracy of the ligation forceps and improving the safety of the operation.
[0094] Regarding the structural setting on the other side of the clamp head 05, as shown in FIG. Fig.18 and Fig.19 As shown, a closing spring piece 12 which is generally V-shaped is provided on an outer wall at the front end of the clamping rod 04 away from the anti-deflection spring piece 044, and both arms of the closing spring piece 12 are inserted between the upper clamp head 051 and the side of the lower clamp head 052 away from the anti-deflection spring piece 044, so that the two arms of the closing spring piece 12 stretch the side of the lower clamp head 052 away from the anti-deflection spring piece 044 and the side of the upper clamp head 051 away from the anti-deflection spring piece 044, thereby closing the upper clamp head 051 and the lower clamp head 052, providing power for closing the clamp head 05.
[0095] In order to allow users to better understand the use of this surgical clip 06 continuous ligation forceps, such as Figures 1 to 5 , Figure 20 to Figure 24As shown, an excitation block 011 which is generally arc-shaped and on the rotation trajectory of the handle 02 is formed in the fixed handle 01, and a plurality of excitation steps 0111 are formed on one end of the excitation block 011 facing the handle 02. An excitation activity plate 021 extending horizontally backward is formed on the handle 02, and an excitation activity step 022 is laterally extended from the tail end of the excitation activity plate 021. The excitation activity plate 021 has no contact with the excitation block 011, and the excitation activity step 022 slides on the plurality of excitation steps 0111. When the handle 02 is pushed, the handle 02 drives the excitation movable plate 021 to rotate toward the clamp head 05, so that the excitation movable step 022 on the excitation movable plate 021 presses against the excitation step 0111, and slides on several excitation steps 0111, thereby providing the user with a sense of passage, and then reminding the user that the excitation control effect has been achieved in the process of clamping, and the step shape of the excitation step 0111 allows the user to judge the progress of the surgical clip 06 tightening through the sense of passage, which is beneficial for the user to control the tightening of the surgical clip 06, improve the accuracy of the surgical clip 06 tightening on the blood vessels and other tissues, and facilitate the operation. After the excitation movable step 022 slides past the excitation step 0111, the user continues to press the handle 02 to make the handle 02 continue to rotate, thereby driving the excitation movable plate 021 and the excitation movable step 022 thereon to reach the highest end of the excitation block 011, and then reset to wait for the next use. The specific method of resetting is that after the handle 02 is released by the user, the handle 02 drives the excitation activity plate 021 and the excitation activity step 022 to rotate backward under the action of its elastic resetting force, so that the excitation activity step 022 bypasses the top of the excitation block 011 to reach the back of the excitation block 011, and slides down along the back of the excitation block 011 to the initial position, completing the resetting. Because the excitation activity plate 021 is not in contact with the excitation block 011, only the excitation activity step 022 is in contact with the excitation block 011, thereby effectively preventing the excitation activity plate 021 from pressing against the excitation block 011 and causing the excitation activity plate 021 to be unable to be reset. The whole process is concise and clear, the structure is simple, and it is easy to cooperate. In addition, the shape of the excitation step 0111 prevents the excitation activity step 022 from retreating, thereby effectively preventing the surgical clip 06 from falling due to sudden release.
[0096] Regarding the specific method of resetting the handle 02, as shown in FIG. Figure 5 , Fig.15 As shown, the handle 02 can be reset by a spring, a spring, etc., and the reset method is a conventional technical means in this field, so it will not be described in detail in this embodiment.
[0097] For other structural settings on the excitation block 011, such as Fig. 22As shown, the end of the excitation block 011 facing the handle 02 is also formed with a confirmation step 0112 located at the upper end of the excitation step 0111, and a reset step 0113 located on the end of the excitation block 011 away from the excitation step 0111. The handle 02 drives the excitation movable plate 021 and the excitation movable step 022 arranged on the excitation movable plate 021 to slide upward into the confirmation step 0112 after sliding through all the excitation steps 0111. At this time, the handle 02 pushes the clamp rod 04 to close the clamp head 05, thereby tightening the surgical clamp 06 on the blood vessel. The segment sense of the confirmation step 0112 reminds the user that the clamping action of the surgical clamp 06 has been completed, which is beneficial for the user to control the tightening situation of the surgical clamp 06. The user continues to push the handle 02, and the handle 02 drives the excitation activity plate 021 and the excitation activity step 022 arranged on the excitation activity plate 021 to continue to slide upward on the excitation block 011 until they enter the reset step 0113. The segment feeling of the reset step 0113 reminds the user that the pressure has been pressed to the end and the ligating forceps will begin to reset, which further helps the user to control the tightening of the surgical clip 06.
[0098] Preferably, Fig. 22 As shown, in order to allow the user to better distinguish whether the ligation forceps is being activated or in place, the step width of the confirmation step 0112 is greater than the step width of the excitation step 0111, so that the paragraph sense when the excitation activity step 022 passes through the confirmation step 0112 is greater than the paragraph sense of the excitation step 0111, thereby allowing the user to better distinguish whether the ligation forceps is being activated or in place, and further facilitating the user's control over the tightening of the surgical clip 06.
[0099] Preferably, Fig. 22 As shown, in order to allow the user to better distinguish whether the ligation is in place or ready to be reset, the step width of the reset step 0113 is greater than the step width of the excitation step 0111, and there is no step between the reset step 0113 and the confirmation step 0112, and the distance between the reset step 0113 and the confirmation step 0112 is relatively far, so that the excitation activity step 022 is obviously smooth and without any jamming from the excitation step 0111 to the confirmation step 0112, and there is an obvious sense of segmentation after reaching the confirmation step 0112, thereby allowing the user to better distinguish whether the ligation forceps is in an activated state, ligation is in place, or ready to be reset, which further helps the user to control the tightening of the surgical clip 06.
[0100] The specific method of sliding the exciting active step 022 on the exciting block 011 is as follows: Fig. 22As shown, the shape of the excitation activity step 022 matches the excitation step 0111, and the raised structure of the step protrudes toward the excitation block 011. The protruding position enters the excitation step 0111, the confirmation step 0112, and the reset step 0113 in sequence under the drive of the handle 02, thereby transmitting the sense of paragraph generated by the collision of the excitation step 0111, the confirmation step 0112, and the reset step 0113 with it, which is beneficial for the user to control the tightening situation of the surgical clip 06.
[0101] Preferably, Fig. 22 As shown, the excitation step 0111, confirmation step 0112 and reset step 0113 are all arranged on the excitation block 011 in an upwardly inclined manner, so as to be more in line with the rotation trajectory of the excitation activity plate 021 and the excitation activity step 022 driven by the handle 02, so that the excitation activity step 022 can slide better and more smoothly on the excitation step 0111, confirmation step 0112 and reset step 0113, which is beneficial to the normal operation of the control device of the excitation handle 02 of the continuous ligating forceps.
[0102] In order to better reset the control device of the trigger handle 02 of the continuous ligating forceps, Fig. 22 As shown, the curvature of the back side of one end of the excitation block 011 close to the reset step 0113 is gentler than the curvature of the back sides of the excitation step 0111 and the confirmation step 0112, so that the excitation activity step 022 can pass over the top of the excitation block 011 and reach the back side of the excitation block 011 more smoothly and easily, thereby improving the reset efficiency and accuracy of the control device of the excitation handle 02 of the continuous ligation forceps.
[0103] Preferably, Fig. 20 and Fig.21 As shown, an identification ruler 13 matching the excitation step 0111, the confirmation step 0112 and the reset step 0113 is arranged on the outer wall of the fixed handle 01, and a first identification arrow 023 pointing to the identification ruler 13 is arranged on the outer wall of the handle 02. The first identification arrow 023 points to different parts of the identification ruler 13 during the rotation of the handle 02, so that the user can judge whether the ligation forceps is in an activated state, ligated in place or ready to be reset from the outside of the ligation forceps, which is further beneficial for the user to control the tightening condition of the surgical clip 06.
[0104] Regarding the specific structural setting of the marking ruler 13, Fig. 20 and Fig.21As shown, the marking ruler 13 includes a length marking block 131 that matches the excitation step 0111, the confirmation step 0112, and the reset step 0113, respectively, a marking text 112 set on the length marking block 131, and a second marking arrow 113 set under the length marking block 131. The length marking block 131 can be set according to the step span of the excitation step 0111, so that the user can also know which excitation step 0111 to rotate to from the external marking ruler 13. The marking text 112 can be set on the length marking block 131 corresponding to the confirmation step 0112 or the reset step 0113, so that the user can know whether the surgical clip 06 has been rotated to the clamping position or the position to be reset, which is further conducive to the user's control of the tightening condition of the surgical clip 06. Each length marking block 131 can also be provided with a marking text 112, so that it is more convenient for the user to observe. Similarly, the second identification arrow 113 points in the direction of the handle 02, and can be separately set on the length identification block 131 corresponding to the confirmation step 0112 or the reset step 0113, so that the user can know whether it has been rotated to the clamping position of the surgical clip 06 or the position ready to be reset. The first identification arrow 023 and the second identification arrow 113 point to each other, which is more convenient for the user to control the tightening status of the surgical clip 06. A second identification arrow 113 can also be set under each length identification block 131, which is more convenient for the user to observe.
[0105] In order to improve the efficiency of the clamp pusher shrapnel 08 in pushing out the surgical clip 06, Figure 25 to Figure 27 As shown, the surgical clip 06 continuous ligation forceps also includes an upper support 09 disposed between one of the outer walls of the clamping chamber rod 04 and the outer sleeve 07. The upper support 09 is formed with at least one convex rib 091 extending radially and facing the clamping chamber rod 04 on the inner wall thereof, and the convex rib 091 is semicircular in shape. When the push-clip spring piece 08 is pushed forward by the push-pull rod 03, the push-clip spring piece 08 slides on the convex rib 091. By setting the convex rib 091 as a semicircular structure, the contact area between the convex rib 091 and the push-clip spring piece 08 is changed from a surface to a point contact, and the contact area is smaller and the friction force is smaller, which effectively prevents the push-clip spring piece 08 from generating excessive friction between the upper support 09, resulting in the problem that the push-clip spring piece 08 cannot slide and is stuck in the ligation forceps and cannot be pushed out, thereby improving the smoothness of the clamping chamber rod 04 being pushed in the upper support, and facilitating the accurate pushing out of the surgical clip 06 in the clamping chamber stem.
[0106] Preferably, Fig. 27As shown, two groups of convex ribs 091 are formed on the upper support member 09, and the two groups of convex ribs 091 are respectively arranged on the upper end and the lower end of the inner wall of the upper support member 09, so that the upper end and the lower end of the outer wall of the push-clamp spring sheet 08 are correspondingly pressed against the two groups of convex ribs 091, and the friction force on the upper end and the lower end of the push-clamp spring sheet 08 is uniform, which effectively prevents the problem of unilateral deviation.
[0107] Regarding the specific structural setting of the outer sleeve 07, Figures 1 to 4 As shown, the outer sleeve 07 is a hollow cylinder as a whole, and the clamping rod 04, the clamping spring 08 and the upper support member 09 are arranged in the hollow position thereof. The cylindrical shape is more conducive to performing actions in the micro-incision of minimally invasive surgery, which is beneficial to the progress of the surgery.
[0108] Preferably, the diameter of the outer sleeve 07 is 9-10 mm, and more preferably, the diameter of the outer sleeve 07 is 9.5 mm, so as to be more suitable for use in minimally invasive surgery.
[0109] The specific method of setting the upper support member 09 on the outer sleeve 07 is as follows: Figure 25 to Figure 27 As shown, one end of the upper support member 09 away from the clamp rod 04 protrudes outward to form a semicircular structure matching the outer sleeve 07, so that the upper support member 09 can be stably pressed against the cylindrical outer sleeve 07, thereby limiting the square clamp rod 04 during the transmission process, preventing the clamp rod 04 from shifting in the outer sleeve 07, resulting in the inability to accurately transmit the surgical clip 06 to the forceps head 05, which is conducive to accurately pushing out the surgical clip 06 in the clamp rod 04.
[0110] The specific method for fixing the upper support member 09 to prevent deviation is as follows: Figure 25 to Figure 27 As shown, the tail end of the upper support member 09 is provided with an upper support limit block 092 which is hollow as a whole and has a semi-arc cross-section. A rotating pin 14 passes through the upper support limit block 092. The rotating pin 14 passes through the upper support limit block 092 and is inserted into the fixed handle 01, thereby limiting the upper support member 09 on the fixed handle 01, thereby preventing the upper support member 09 from shifting.
[0111] Preferably, Figure 25 to Figure 26 as well as Fig.28As shown, in order to better limit the position of the clamp rod 04, the surgical clip 06 continuous ligation forceps further includes a lower support 10 disposed between the clamp rod 04 and the outer sleeve 07 and symmetrical to the upper support 09. The clamp rod 04 and the clamp push spring piece 08 are clamped and limited relative to each other by the upper support 09 and the lower support 10, so that the clamp rod 04 and the clamp push spring piece 08 are less likely to shift in the outer sleeve 07, which is conducive to accurately pushing out the surgical clip 06 in the clamp rod 04.
[0112] Preferably, Figures 1 to 4 As shown, a rotating head 15 may also be provided on the fixed handle 01, and the rotating pin 14 is inserted into the inner wall of the rotating head 15, thereby driving the clamp rod 04, the clamp push spring 08, etc. to rotate along with the rotating head 15, so that the surgical clamp 06 can be rotated to different angles, which is beneficial to the operation.
[0113] The specific method of setting the lower support member 10 on the outer sleeve 07 is as follows: Figure 25 to Figure 26 as well as Fig.28 As shown, one end of the lower support member 10 away from the clamping magazine rod 04 protrudes outward to form a semicircular structure matching the outer sleeve 07, so that the lower support member 10 can be stably pressed against the cylindrical outer sleeve 07, thereby achieving the purpose of limiting the square clamping magazine rod 04 during the transmission process, preventing the clamping magazine rod 04 from shifting in the outer sleeve 07, resulting in the surgical clip 06 being unable to be accurately transmitted to the forceps head 05, and facilitating the precise ejection of the surgical clip 06 in the clamping magazine rod 04.
[0114] The specific method for fixing the lower support member 10 to prevent deviation is as follows: Figure 25 to Figure 26 as well as Fig.28 As shown, the tail end of the lower support member 10 is provided with a lower support stopper 101 which is hollow as a whole and has a semi-arc cross section and matches the upper support stopper 092. The rotating pin 14 sequentially passes through the upper support stopper 092 and the lower support stopper 101 and is inserted into the fixed handle 01 at both ends, thereby limiting the lower support member 10 and the upper support member 09 on the fixed handle 01, thereby preventing the upper support member 09 and the lower support member 10 from shifting. The upper support stopper 092 and the lower support stopper 101 are mutually engaged to form a hollow cylinder, and the clamp rod 04 and the clamp push spring sheet 08 are placed in the hollow position of the cylinder, thereby effectively limiting the clamp rod 04 and the clamp push spring sheet 08, preventing the clamp rod 04 from shifting in the outer sleeve 07, resulting in the inability to accurately transfer the surgical clip 06 to the clamp head 05, and facilitating the accurate pushing of the surgical clip 06 in the clamp rod 04.
[0115] In order to further improve the smoothness of the pushing clip spring 08 in pushing the surgical clip 06, as shown in FIG. Figure 5 , Fig.15 , Figure 29 to Figure 31 As shown, the surgical clip 06 continuous ligation forceps also includes a support bar 11 which is arranged in the push-pull rod 03 and pushes the push-clamp spring piece 08. The upper end and the lower end of the support bar 11 are formed with a plurality of convex points 111 which are arranged and protruded in sequence toward the inner wall direction of the clamp magazine rod 04. When the support bar 11 drives the push-clamp spring piece 08 to be pushed out, the convex points 111 on the support bar 11 are respectively pressed against the upper inner wall and the lower inner wall of the clamp magazine rod 04, so that the contact between the support bar 11 and the clamp magazine rod 04 is changed from surface contact to point contact, which effectively reduces the contact area, improves the smoothness of the support bar 11 when driving the push-clamp spring piece 08 to move forward, and is conducive to accurately pushing out the surgical clip 06 in the clamp magazine rod 04.
[0116] Regarding the specific method in which the push-clip spring piece 08 is pushed out by the support bar 11, Figure 7 as well as Fig.30 and Fig.31 As shown, a push clamp limiting groove 112 for inserting the push clamp spring piece 08 is formed on the side of the support bar 11 away from the clamping magazine rod 04, and a push clamp limiting block 083 is formed on the side of the push clamp spring piece 08 facing the support bar 11, which protrudes inward and slides in the push clamp limiting groove 112. The push clamp limiting block 083 slides in the push clamp limiting groove 112, and the push clamp limiting block 083 is limited in the up and down directions by the push clamp limiting groove 112, thereby effectively preventing the push clamp spring piece 08 from deviating during the process of being driven to move, which is conducive to accurately pushing out the surgical clamp 06 in the clamping magazine rod 04.
[0117] The specific method for preventing the support bar 11 from deflecting when being pushed by the push-pull rod 03 is as follows: Fig.30 and Fig.31 As shown, one end of the support bar 11 close to the push-pull rod 03 is provided with a first push limit groove 113 extending radially in the direction of the push-pull rod 03, and the rotating pin 14 passes through the first push limit groove 113 and the clamping rod 04 and then is clamped into the inner wall of the fixed handle 01. When the push-pull rod 03 is pushed, the first push limit groove 113 in the support bar 11 moves forward and backward relative to the rotating pin 14 fixed on the inner wall of the fixed handle 01, thereby realizing the travel limiting effect of the first push limit groove 113 and preventing the support bar 11 from being offset when being pushed by the push-pull rod 03.
[0118] Preferably, Figure 7 as well as Fig.30 and Fig.31As shown, in order to synchronously push the push-clamp spring piece 08, a second push limit groove 084 matching the first push limit groove 113 is formed at the tail end of the push-clamp spring piece 08, and the rotating pin 14 sequentially passes through the second push limit groove 084, the first push limit groove 113 and the clamping magazine rod 04 and then is clamped into the inner wall of the fixed handle 01. When the push-pull rod 03 is pushed, the first push limit groove 113 in the support bar 11 and the second push limit groove 084 on the push-clamp spring piece 08 move forward and backward relative to the rotating pin 14 fixed on the inner wall of the fixed handle 01, thereby realizing the travel limiting effect of the first push limit groove 113 and the second push limit groove 084, preventing the support bar 11 and the push-clamp spring piece 08 from shifting during the pushing process, and at the same time realizing the synchronous limiting of the support bar 11 and the push-clamp spring piece 08, which is beneficial to the purpose of the support bar 11 driving the push-clamp spring piece 08.
[0119] Regarding the length setting of the first pushing limit groove 113 and the second pushing limit groove 084, the length of the first pushing limit groove 113 and the second pushing limit groove 084 is equal to the distance between the two groups of surgical clips 06 in the clamping magazine rod 04, so that the limiting stroke of the rotating pin 14 to the support bar 11 and the pushing clamp spring piece 08 is the stroke for pushing out a group of surgical clips 06, which is conducive to accurately pushing out each group of surgical clips 06 separately.
[0120] Preferably, Figure 7 as well as Fig.30 and Fig.31 As shown, in order to enable the push-pull rod 03 to better push the push-clamp spring piece 08, the tail end of the push-clamp spring piece 08 is formed with a support linkage limit block 085 which is bent toward the inner wall direction of the clamping rod 04 to press the tail end of the support bar 11 to limit the position. When the push-pull rod 03 pushes the support bar 11, the support linkage limit block 085 presses on the tail end of the support bar 11, thereby improving the linkage between the support bar 11 and the push-clamp spring piece 08, so that the push-pull rod 03 can better push the push-clamp spring piece 08, which is beneficial to the coordination between the various components.
[0121] Regarding the specific manner in which the support bar 11 and the push-clamp spring piece 08 are arranged in the push-pull rod 03, as shown in FIG. Figure 7 as well as Figure 30 to Figure 32 As shown, one end of the push-pull rod 03 close to the support bar 11 is formed with a push-pull embedding groove 031 extending inward and for the support bar 11 and the push-clamp spring piece 08 to be embedded in. The support bar 11 and the push-clamp spring piece 08 are correspondingly embedded in the push-pull embedding groove 031, so that the push-pull rod 03 can stably drive the push-clamp spring piece 08 and the support bar 11 to push out and retract and reset, thereby ensuring the normal operation of the ligating forceps.
[0122] The specific way in which the support bar 11 and the push-clamp spring piece 08 are driven in the push-pull rod 03 is as follows: Fig.30 and Fig.31 As shown, a push-pull fixing hole 114 is vertically provided at one end of the support bar 11 close to the push-pull rod 03, and the push-pull pin 16 passes through the push-pull rod 03 and the push-pull fixing hole 114 to fix the push-pull rod 03 and the support bar 11 in the push-pull embedding groove 031, so that the push-pull rod 03 can stably drive the push-clamp spring piece 08 and the support bar 11 to push out and retract and reset, which is beneficial to the coordination between the various components.
[0123] Regarding the resetting method of the support bar 11 when it is displaced in the push-pull rod 03 , a spring may be provided between the tail end of the support bar 11 and the inner wall of the push-pull rod 03 , so that the support bar 11 can be reset by the spring when it moves.
