Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a ligation device for ligating blood vessels during surgery and a filling method for ligation locks. Background Art

[0002] During a surgical operation, it is usually necessary to separate the relevant arteries and veins involved in the surgical site through a ligation device such as a hemostat or a clip applicator and then perform ligation in order to complete the resection of the subsequent surgical site.

[0003] Existing ligation devices require a surgical nurse to install a ligation lock and hand the ligation device to the surgeon. After that, the surgeon inserts the ligation device into the patient's body through a puncture hole to perform ligation on the blood vessels, and then takes out the ligation device from the patient's body and passes it to the surgical nurse to complete the installation of a new ligation lock, and then passes it to the doctor. The doctor then re-inserts the ligation device into the patient's body to complete the clamping. This process is repeated, with complex operations. It not only prolongs the operation time and increases the multiple injuries caused by the repeated entry and exit of the instrument into the patient's abdominal cavity, but also because some blood vessels require multiple ligation locks to complete the complete ligation of the blood vessels, the loading time of the ligation locks significantly increases the patient's blood loss during the operation and increases the patient's surgical risk.

Detailed implementation manners

[0052] In order to enable those skilled in the art to better understand the solution of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0053] The following further details the present application with reference to the accompanying drawings of the specification.

[0054] The embodiments of the present application disclose a ligation device for ligating blood vessels during surgery and a filling method for ligature locks.

[0055] As Figure 1 and Figure 2 shown, a ligation device for ligating blood vessels during surgery includes a ligation operation assembly 1, a ligature forceps 2, an automatic loading assembly 3 and a ligature lock 4; the ligature forceps 2 is arranged on the ligation operation assembly 1, and the ligation operation assembly 1 is used to drive the ligature forceps 2 to open or close; the automatic loading assembly 3 is arranged on the ligation operation assembly 1; a plurality of ligature locks 4 are arranged, and the plurality of ligature locks 4 are arranged on the automatic loading assembly 3, and the automatic loading assembly 3 is used to sequentially load the ligature locks 4 onto the ligature forceps 2.

[0056] The plurality of ligature locks 4 are arranged on the automatic loading assembly 3. During use, the plurality of ligature locks 4 can be sequentially loaded onto the ligature forceps 2 by the automatic loading assembly 3.

[0057] After the operator operates the ligation operation assembly 1 to close the ligature forceps 2, the ligature lock 4 on the ligature forceps 2 can successfully ligate the position to be operated. Then, the ligature forceps 2 is opened, and the automatic loading assembly 3 can automatically send the next ligature lock 4 to the ligature forceps 2 for the next ligation operation.

[0058] During the whole process, the automatic loading of the ligation lock 4 onto the ligating forceps 2 is realized, solving the problem that the existing ligation device needs to be repeatedly withdrawn from the patient's body for loading the ligation lock 4 during the ligation operation.

[0059] As Figure 1 and Figure 2 shown, the automatic loading assembly 3 includes a loading member 31 and an elastic pushing member 32; the loading member 31 is arranged on the ligation operation assembly 1, and the elastic pushing member 32 is arranged on the loading member 31; a plurality of ligation locks 4 are sequentially arranged on the loading member 31, and one end of the elastic pushing member 32 abuts against the ligation lock 4 located at the edge; the elastic pushing member 32 has elastic potential energy to push the plurality of ligation locks 4 in the direction close to the ligating forceps 2.

[0060] Specifically, the ligation operation assembly 1 includes a handle 11 and a shaft rod 12.

[0061] The handle 11 is designed as an ergonomic grip, which includes a locking device to fix the closed state of the ligating forceps 2.

[0062] The shaft rod 12 is made of stainless steel or polymer material and needs to have the characteristics of being light and corrosion-resistant.

[0063] The shaft rod 12 is connected between the ligating forceps 2 and the handle 11. During actual operation, the doctor holds and presses the handle 11, and transmits mechanical force to the ligating forceps 2 through a connecting rod or a steel wire, thereby controlling the opening or closing of the ligating forceps 2.

[0064] The loading member 31 is arranged on the shaft rod 12, and the elastic pushing member 32 is arranged on the loading member 31. The elastic pushing member 32 can be compressed or stretched along the axial direction of the shaft rod 12.

[0065] It should be noted that for the convenience of the ligation device for ligating blood vessels during surgery to enter the patient's body, both the loading member 31 and the shaft rod 12 are semi-circular rods with a semi-circular cross-section, and the cross-sectional radii of the loading member 31 and the shaft rod 12 are the same. After the loading member 31 is arranged on the shaft rod 12, the cross-section of the loading member 31 and the shaft rod 12 is a complete circle.

[0066] A plurality of ligation locks 4 are sequentially arranged along the axial direction of the shaft rod 12, and a plurality of ligation locks 4 are sequentially arranged in front of the elastic pushing member 32.

[0067] The opening of each ligation lock 4 is arranged in the direction close to the ligating forceps 2.

[0068] When ligating blood vessels using a ligating device for surgical blood vessel ligation, multiple ligation locks 4 are pushed forward by an elastic pusher 32. The ligation lock 4 at the forefront will fall onto the lower ligating forceps 2 for subsequent ligation operations. Since there is already a ligation lock 4 on the ligating forceps 2, the rear ligation locks 4 will not fall onto the ligating forceps 2 again until after the ligation operation of one blood vessel is completed. When the position for the ligation lock 4 on the ligating forceps 2 becomes vacant, the rear ligation locks 4 will automatically continue to fall onto the ligating forceps 2 under the push of the elastic pusher 32 for subsequent ligation operations.

[0069] As Figure 1 and Figure 2 shown, a receiving space is formed inside the loading member 31, and the elastic pusher 32 is disposed on the inner wall of the receiving space on the side away from the ligating forceps 2; multiple ligation locks 4 are sequentially disposed inside the receiving space; the loading member 31 is provided with a loading hole 311, the loading hole 311 is located above the ligating forceps 2, and the loading hole 311 communicates with the receiving space.

[0070] Specifically, both the elastic pusher 32 and the ligation lock 4 are disposed inside the receiving space. One end of the elastic pusher 32 is disposed on the inner wall of the loading member 31 at the end away from the ligating forceps 2, and the other end abuts against the adjacent ligation lock 4.

[0071] When multiple ligation locks 4 are all loaded into the receiving space, the elastic pusher 32 is in a compressed state to facilitate the elastic pusher 32 to push multiple ligation locks 4 forward to achieve automatic filling of the ligation locks 4 inside the ligating forceps 2.

[0072] Both the elastic pusher 32 and the ligation lock 4 are disposed inside the receiving space. On the one hand, it can prevent the ligation lock 4 from falling due to shaking during the use of the ligating device for surgical blood vessel ligation. On the other hand, it can improve the sealing performance between the ligation lock 4 and the elastic pusher 32 to prevent direct contact with the outside.

[0073] And providing the loading hole 311 directly above the ligating forceps 2 can facilitate the ligation lock 4 inside the receiving space to smoothly pass through under the push of the elastic pusher 32 and fall onto the ligating forceps 2 for ligation operations.

[0074] As Figure 1 、 Figure 2 and Figure 5 shown, a guiding inclined surface 312 is provided on the inner wall of the loading member 31 close to the ligation lock 4, and the guiding inclined surface 312 is used to guide the ligation lock 4 to pass through the loading hole 311.

[0075] Specifically, the guiding inclined surface 312 is located above the loading hole 311. When the ligation lock 4 at the foremost position (i.e., the ligation lock 4 at the end far from the elastic pushing member 32) moves forward under the pushing action of the elastic pushing member 32, the ligation lock 4 at the foremost position will abut against the upper guiding inclined surface 312 and be squeezed to move downward, so as to pass through the loading hole 311 and fall onto the lower ligation forceps 2.

[0076] As Figure 1 , Figure 2 and Figure 10 shown, a blocking fence 23 is provided on the upper outer edge of the ligation forceps 2, and the blocking fence 23 is used to prevent the ligation lock 4 from falling off the ligation forceps 2.

[0077] Specifically, the ligation forceps 2 includes a first forceps arm 21 and a second forceps arm 22, and both the first forceps arm 21 and the second forceps arm 22 are provided at one end of the shaft rod 12.

[0078] Under the control of the ligation operation assembly 1, the first forceps arm 21 and the second forceps arm 22 can be opened or closed.

[0079] The shape of the blocking fence 23 is similar to the outer shape of the ligation forceps 2, and the blocking fence 23 is provided on the outer edges of the upper surfaces of both the first forceps arm 21 and the second forceps arm 22.

[0080] The setting of the blocking fence 23 enables the ligation lock 4 that has fallen onto the ligation forceps 2 to be surrounded by the blocking fence 23, thereby preventing the ligation lock 4 from falling to the outside.

[0081] It should be noted that for the convenience of the ligation lock 4 to be buckled to complete the ligation operation, the blocking fence 23 only surrounds the outer edge of the ligation forceps 2, and the inner edges of the first forceps arm 21 and the second forceps arm 22 are not provided with the blocking fence 23.

[0082] As Figure 2 , Figure 3 and Figure 4 shown, a replenishing hole 313 is provided on the loading member 31, the replenishing hole 313 is communicated with the accommodating space, and the replenishing hole 313 is used to fill the ligation lock 4 into the accommodating space; a blocking member 314 is detachably provided on the replenishing hole 313.

[0083] Specifically, the replenishing hole 313 is provided at the top of the loading member 31, which is convenient for medical staff to fill the ligation lock 4 into the accommodating space.

[0084] At the same time, the blocking member 314 is slidably provided on the replenishing hole 313. The blocking member 314 can be slid out from the loading member 31 to replenish the ligation lock 4 into the accommodating space. After replenishment, the blocking member 314 is reinstalled to maintain the airtightness of the accommodating space.

[0085] Further, dovetail grooves 3131 are provided on the relative inner walls of the supplementary holes 313, and dovetail bars 3141 that cooperate with the dovetail grooves 3131 are provided on both sides of the plugging member 314. Through the cooperation of the dovetail grooves 3131 and the dovetail bars 3141, the plugging member 314 is slidably provided on the supplementary hole 313.

[0086] The dovetail grooves 3131 and the dovetail bars 3141 are of special shapes, trapezoidal or similar to trapezoidal. The two are embedded and cooperate with each other to form a tight connection, which has a good limiting effect. Without applying external force, it can effectively prevent relative sliding or detachment between the plugging member 314 and the loading member 31, and can make the structure more stable.

[0087] Furthermore, sliding ridges can be provided on the plugging member 314 to facilitate sliding out of the plugging member 314.

[0088] Such as Figure 2 and Figure 6 As shown, the elastic pushing member 32 includes an elastic telescopic member 321 and an auxiliary pushing member 322. One end of the elastic telescopic member 321 is provided on the inner wall of the accommodation space on the side away from the ligating forceps 2, and the other end is provided with the auxiliary pushing member 322. The auxiliary pushing member 322 abuts against the ligating lock 4 located at the edge; a sliding hole 315 is provided on the loading member 31, and part of the auxiliary pushing member 322 extends out from the sliding hole 315.

[0089] Specifically, the sliding hole 315 is provided on any one of the two side walls of the loading member 31 or the sliding hole 315 is provided on both side walls of the loading member 31.

[0090] The sliding hole 315 is a strip-shaped hole, and the length direction of the sliding hole 315 is arranged along the axial direction of the shaft rod 12.

[0091] The elastic telescopic member 321 is an elastic spring. When it is necessary to load the ligating lock 4 into the accommodation space, the plugging member 314 is removed from the loading member 31, and the pushing portion 3222 is pushed to drive the abutting portion 3221 to compress the elastic telescopic member 321. Since the elastic telescopic member 321 is compressed, a free space is left in the accommodation space, and at this time, the ligating lock 4 can be loaded into the free space.

[0092] Such as Figure 2 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, the auxiliary pushing member 322 includes an abutting portion 3221 and a pushing portion 3222; the abutting portion 3221 is provided at one end of the elastic telescopic member 321, and the pushing portion 3222 is provided on the abutting portion 3221; a groove 317 is provided on the loading member 31, the sliding hole 315 is provided at the bottom of the groove 317, and the outermost surface of the pushing portion 3222 is flush with the notch of the groove 317.

[0093] Specifically, the abutting portion 3221 is used to push the ligation lock 4 to move in the axial direction of the shaft rod 12, and the pushing portion 3222 is arranged on the abutting portion 3221. The pushing portion 3222 extends out of the sliding hole 315 and the pushing portion 3222 abuts against the bottom of the groove 317.

[0094] The design of the groove 317 enables the loading member 31 not to generate additional protrusions due to the arrangement of the pushing portion 3222, reducing the risk of additional damage to the patient caused by phenomena such as rubbing when the ligation device for surgical blood vessel ligation is inserted into the body.

[0095] Furthermore, the outermost surface of the pushing portion 3222 is provided with friction lines 3222a for facilitating pushing.

[0096] Such as Figure 2 and Figure 6 As shown, guide rails 316 are arranged on the inner wall of the loading member 31, and guide grooves 41 are arranged on multiple ligation locks 4. The guide rails 316 are slidably connected to the guide grooves 41 of each ligation lock 4.

[0097] Specifically, the guide rails 316 are arranged on the bottom wall of the loading member 31, and the guide rails 316 are arranged along the axial direction of the shaft rod 12 (i.e., the guide rails 316 are in the same direction as the direction in which the ligation lock 4 is pushed). The cooperation between the guide rails 316 and the guide grooves has the function of guiding and positioning, which can not only ensure the movement accuracy of the ligation lock 4, provide an accurate movement trajectory for the ligation lock 4, and enable it to move linearly along the axial direction of the shaft rod 12, but also maintain the movement stability, enable the ligation lock 4 to remain stable during the movement, and prevent situations such as deviation and shaking.

[0098] Furthermore, to enhance the stability of the auxiliary pushing member 322 for pushing, the bottom of the abutting portion 3221 can also have a guide groove 41 that is slidably engaged with the guide rail 316.

[0099] Such as Figure 11 As shown, a filling method for a ligation lock is applied to the ligation device for surgical blood vessel ligation described in any one of the above, and the method includes:

[0100] S100. Compress the elastic pushing member 32, and sequentially place multiple ligation locks 4 on the loading member 31, wherein the openings of each ligation lock 4 are arranged in a direction away from the elastic pushing member 32.

[0101] Specifically, when the ligation lock 4 needs to be loaded into the accommodation space, the plugging member 314 is removed from the loading member 31, the pushing portion 3222 is pushed, driving the abutting portion 3221 to compress the elastic telescopic member 321. Since the elastic telescopic member 321 is compressed, a free space is left in the accommodation space, and at this time, the ligation lock 4 can be loaded into the free space.

[0102] Each loading of the ligation lock 4 is maintained with the opening facing away from the elastic pusher 32, so as to ensure that after the ligation lock 4 is pushed onto the ligating forceps 2, the opening of the ligation lock 4 can face the outside, meeting the requirements of the ligation operation.

[0103] Moreover, the placement of the ligation locks 4 must ensure that the guiding grooves 41 on each ligation lock 4 are inserted onto the guide rails 316 to maintain the moving stability of the ligation locks 4 during the pushing process.

[0104] After all the ligation locks 4 to be loaded are filled into the accommodating space, the sealing member 314 is reinstalled onto the loading member 31 to ensure the airtightness of the accommodating space.

[0105] In summary, a ligation device for ligating blood vessels in surgery includes a ligation operation assembly 1, ligating forceps 2, an automatic loading assembly 3, and ligation locks 4; the ligating forceps 2 are arranged on the ligation operation assembly 1, and the ligation operation assembly 1 is used to drive the ligating forceps 2 to open or close; the automatic loading assembly 3 is arranged on the ligation operation assembly 1; there are multiple ligation locks 4, and the multiple ligation locks 4 are arranged on the automatic loading assembly 3, and the automatic loading assembly 3 is used to sequentially load the ligation locks 4 onto the ligating forceps 2.

[0106] The multiple ligation locks 4 are arranged on the automatic loading assembly 3. During use, the multiple ligation locks 4 can be sequentially loaded onto the ligating forceps 2 by the automatic loading assembly 3.

[0107] After the operator operates the ligation operation assembly 1 to close the ligating forceps 2, the ligation lock 4 on the ligating forceps 2 can successfully ligate the position to be operated. Then, the ligating forceps 2 are opened, and the automatic loading assembly 3 can automatically send the next ligation lock 4 to the ligating forceps 2 for the next ligation operation.

[0108] Throughout the process, automatic loading of the ligation locks 4 onto the ligating forceps 2 is achieved, solving the problem that the existing ligation device needs to be repeatedly withdrawn from the patient's body for loading the ligation locks 4 during the ligation operation.

[0109] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0110] It should be noted that the present invention takes a ligation device for ligating blood vessels in surgery and a filling method of the ligation lock as an example to introduce the specific structure and working principle of the present invention. However, the application of the present invention is not limited to a ligation device for ligating blood vessels in surgery and a filling method of the ligation lock, and can also be applied to the production and use of other similar workpieces.

[0111] It should be understood that the present invention is not limited to the exact structures described above and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the present invention is only limited by the appended claims.
