Description

Technical Field

[0001] The invention belongs to the technical field of medical instruments, and in particular relates to a reusable quick-detachable tissue clamp. Background Art

[0002] During clinical laparoscopic surgery, tissue clamps are usually used to clamp tissues to prevent bleeding. At present, tissue clamps that can be stimulated multiple times continuously are mostly used. Although this type of tissue clamp does not need to be removed from the body and reinstalled after completing a tissue clamp, the connecting components of the tissue clamp will extend into the patient's body and contact the patient's muscle tissue, blood, body fluids, etc. during use. Therefore, each set of tissue clamps can only be used by one patient to avoid the risk of infection. In this way, the stimulation device that has not come into contact with the patient's muscle tissue, blood, body fluids, etc. will also be scrapped, which not only increases the cost of the operation and wastes a lot of resources. At the same time, the stimulation device is mostly made of plastic. As we all know, the degradation rate of plastic waste is very slow and is the main source of environmental pollution. Therefore, it is necessary to develop a reusable quick-disassembly and assembly tissue clamp. Summary of the invention

DETAILED DESCRIPTION

[0039] The present invention will now be further described in detail with reference to embodiments.

[0040] A reusable quick-release tissue clamp, such as Figure 1 As shown, it includes an excitation device 1, a clamping head assembly 2 and a connecting assembly 3 for connecting the excitation device 1 and the clamping head assembly 2, and the connecting assembly 3 is detachably fixed in the excitation device 1.

[0041] In a specific embodiment, Figure 2 , Figure 5 and Figure 6 As shown, the connecting component 3 includes a connecting sleeve 31 and a driving mechanism 32 arranged in the connecting sleeve 31 for connecting the excitation device 1 and the chuck assembly 2, and a pin hole for fixing the connecting component 3 is provided on the connecting sleeve 31; the excitation device 1 is provided with a fixing hole at one end close to the chuck assembly 2, and a fixing pin 112 is fixed in the fixing hole and can slide up and down along the inner wall of the fixing hole for a set distance; after one end of the connecting component 3 is inserted into the excitation device 1, it is rotated at a certain angle so that the fixing pin 112 is inserted into the pin hole to fix the connecting component 3.

[0042] In a specific embodiment, Figure 5As shown, a sliding groove is provided on the inner wall of the fixing hole, and a sliding protrusion matching the sliding groove is provided on the outer wall of the fixing pin 112. The cooperation between the sliding protrusion and the sliding groove can fix the fixing pin 112 in the fixing hole and slide up and down along the inner wall of the fixing hole for a set distance. After inserting one end of the connecting component 3 into the excitation device 1, rotate it clockwise by a certain angle (for example, rotate it by 45°), press the fixing pin 112, and insert the fixing pin 112 into the pin hole to fix the connecting component 3. When it is necessary to pull out the connecting component 3, just pull the fixing pin 112 out of the pin hole by a set distance along the fixing hole, and then rotate the connecting component 3 counterclockwise by a certain angle (for example, rotate it by 45°) to pull out the connecting component 3. In a specific embodiment, the position of the pin hole can be marked on the connecting sleeve 31 to facilitate accurate rotation into place.

[0043] In a specific embodiment, the distance that the sliding protrusion can slide up and down in the sliding groove can be 0.5-2 mm, preferably 1 mm.

[0044] In a specific embodiment, Figure 1 and Figure 2 As shown, the excitation device 1 includes a conical fixing cover 11 disposed at one end close to the clamp assembly 2, a fixing hole is disposed on the conical fixing cover 11, and the connecting assembly 3 is inserted into the excitation device 1 through the conical fixing cover 11. Fig.10 As shown, the conical fixing cover 11 has a circular hole at one end close to the clamping assembly 2, and the connecting assembly 3 can be directly inserted into the excitation device 1 through the circular hole.

[0045] In a specific embodiment, Figure 2-3 As shown, the excitation device 1 also includes an excitation handle 12, an excitation trigger 13 and an excitation push rod 14. The excitation push rod 14 is arranged in the excitation handle 12 and is slidably connected to the connecting sleeve 31. The excitation trigger 13 is rotatably fixed on the excitation handle 12 and is used to drive the excitation push rod 14 to push the driving mechanism 32 forward.

[0046] In a specific embodiment, Figure 5-8 As shown, the connection assembly 3 also includes a tissue clip positioning device 33, which is used to accommodate the tissue clip 9 and position the tissue clip 9 after it is pushed forward one step; the connection sleeve 31 includes two upper and lower arc-shaped wrapping sheets 311 wrapped around the outer side of the tissue clip positioning device 33 and the driving mechanism 32, a wrapping sleeve 312 sleeved outside the arc-shaped wrapping sheet 311, and a propulsion limiting sleeve 313 fixedly connected to the two arc-shaped wrapping sheets 311. After the connection assembly 3 is inserted into the excitation device 1, the propulsion limiting sleeve 313 is slidably connected to the excitation push rod 14. The outer diameter of the excitation push rod 14 is less than or equal to the inner diameter of the propulsion limiting sleeve 313. After the connection assembly 3 is inserted into the excitation device 1, the excitation push rod 14 is inserted into the propulsion limiting sleeve 313 to achieve a sliding connection.

[0047] In a continuous-fire tissue clamp, after the tissue clamp is extended into the human body, it is usually necessary to fire multiple tissue clamps to clamp multiple blood vessels, tissues, etc. Therefore, the tissue clamp positioning device 33 of the continuous-fire tissue clamp can accommodate multiple tissue clamps 9 at the same time. Each time the trigger 13 is squeezed, the excitation push rod 14 will drive the driving mechanism 32 to push all the tissue clips 9 in the tissue clip positioning device 33 forward one step. After being pushed forward one step, the tissue clips 9 are positioned by the positioning device on the tissue clip positioning device 33.

[0048] In a specific embodiment, Figure 3 As shown, the excitation push rod 14 includes a push rod seat 141 and a push rod barrel 142 that are fixedly connected; the connection assembly 3 also includes a reset spring 34 for resetting the tissue clamp; the advancement limiting sleeve 313 has an annular boss 3131 protruding outward along the outer wall at one end close to the arc-shaped package sheet 311, and the reset spring 34 is sleeved on the outer side of the advancement limiting sleeve 313, and one end is fixed on the annular boss 3131. The end of the push rod barrel 142 close to the connection assembly 3 extends into the advancement limiting sleeve 313, so that a part of the reset spring 34 is sleeved on the push rod barrel 142, and the other end of the reset spring 34 is against the push rod seat 141. In the process of driving the push rod seat 141 to push the driving mechanism 32 forward by grasping the excitation trigger 13, the reset spring 34 is compressed by pressure, and then the reset spring 34 resists the pressure and stretches, pushing the push rod seat 141 and driving the excitation trigger 13 to reset, so as to facilitate the next excitation.

[0049] In a specific embodiment, Figure 3 As shown, a connecting rod is fixedly connected to the rear side of the push rod seat 141, and a disc is fixedly connected to the rear side of the connecting rod. The entire excitation push rod 14 is limited in the excitation device 1 by the disc, and the top of the excitation trigger 13 is divided into two parts, so that in the process of grasping the excitation trigger 13 to push the excitation push rod 14 forward, the top of the excitation trigger 13 can effectively avoid the connecting rod.

[0050] In a specific embodiment, Figure 6 As shown, the push rod tube 142 is symmetrically provided with two through holes on the side wall near one end of the connecting component 3, and the push rod pins 8 are passed through the two through holes; the driving mechanism 32 is provided with a pin groove 321 at one end near the excitation push rod 14, so that the push rod pin 8 can be accommodated in the pin groove 321 after the connecting component 3 is inserted into the excitation device 1.

[0051] In a specific embodiment, a pressure spring is fixedly arranged in the push rod barrel 142, and the pressure spring is restricted in the push rod barrel 142 by the push rod pin 8. The pressure spring presses against the push rod pin 8 to firmly fix the push rod pin 8, thereby avoiding unstable assembly of the push rod pin 8 and slipping due to errors generated during the parts manufacturing process.

[0052] In a specific embodiment, Figure 7 As shown, the excitation push rod 14 is symmetrically provided with two U-shaped grooves 143 on the side wall near one end of the connecting component 3; the driving mechanism 32 is penetrated by a push rod pin 8 at one end near the excitation device 1, and after the connecting component 3 is inserted into the excitation device 1, the two ends of the push rod pin 8 are respectively accommodated in the two U-shaped grooves 143.

[0053] In a specific embodiment, a pressure spring is fixedly disposed in the push rod tube 142 , and the pressure spring can provide a stress for the driving mechanism to make the connection between the components tighter.

[0054] In a specific embodiment, Figure 3 , Figure 6-8 As shown, two strip holes 3132 are symmetrically arranged on the side wall of the propulsion limiting sleeve 313 for accommodating the push rod pin 8 and allowing the push rod pin 8 to move forward and backward a certain distance. The plane where the longitudinal axes of the two strip holes 3132 are located divides the propulsion limiting sleeve 313 into two upper and lower half-limiting sleeves 3130, and divides each strip hole 3132 into two strip grooves 31321. The two half-limiting sleeves 3130 are respectively integrally formed with the two arc-shaped wrapping plates 311.

[0055] The arrangement of the strip hole 3132 allows the push rod pin 8 to advance a set distance therein, thereby pushing the driving mechanism 32 forward while keeping the propulsion limiting sleeve 313 (i.e., the entire connecting sleeve 31) stationary. The propulsion limiting sleeve 313 is evenly divided into two upper and lower half limiting sleeves 3130, which is convenient for assembly on the one hand, and on the other hand, when using Figure 6 In the embodiment shown, when the entire connecting assembly 3 is pulled out, the push rod pin 8 can be smoothly separated from the advancement limiting sleeve 313.

[0056] In a specific embodiment, Figure 6-7 and Fig. 9 As shown, each semi-restriction sleeve 3130 may be provided with a mating protrusion 31302 and a mating groove 31303 on both sides of the position where the annular boss 3131 is provided. During assembly, the mating protrusion 31302 of one semi-restriction sleeve 3130 is inserted into the mating groove 31303 of the other semi-restriction sleeve 3130 to achieve positioning.

[0057] In a specific embodiment, Figure 6As shown, the strip groove 31321 of each semi-restriction sleeve 3130 is provided with a circular arc chamfer 31322 at the end close to the push rod tube 142, so that the push rod pin 8 can smoothly detach from the push restriction sleeve 313 when the connecting component 3 is pulled out of the excitation device 1; each semi-restriction sleeve 3130 is provided with a circular arc chamfer 31301 at the end close to the push rod tube 142, so that the push rod pin 8 can smoothly slide into the strip hole 3132 when the connecting component 3 is inserted into the excitation device 1.

[0058] In a specific embodiment, Figure 6-9 As shown, the connecting assembly 3 also includes a limiting rod 35, which is used to limit the position of each component during the rotation of the connecting assembly 3; the tissue clamp positioning device 33 is provided with a limiting hole 1 331 at one end close to the excitation device 1, and the advancement limiting sleeve 313 is provided with two symmetrical limiting holes 2 3133 at the corresponding position, and the limiting rod 35 passes through a limiting hole 2 3133, the limiting hole 1 331 and the other limiting hole 2 3133 in sequence; the driving mechanism 32 is provided with a strip avoidance hole 322 at a position corresponding to the limiting rod 35, so that the driving mechanism 32 can avoid the limiting rod 35 and advance a set distance.

[0059] The setting of the limit rod 35 can avoid the situation that the rotation angles of the components are inconsistent during the rotation process after the connecting component 3 is inserted into the stimulating device 1, thereby ensuring the accuracy of the tissue clamp. After the tissue clamp is stimulated, the connecting sleeve 31 and the tissue clamp positioning device 33 both maintain their original positions, and the tissue clamp 9 in the tissue clamp positioning device 33 is pushed forward by the driving mechanism 32, and the strip avoidance hole 322 can avoid the driving mechanism 32 from being blocked.

[0060] In a specific embodiment, the second limiting hole 3133 can be a circle that can only accommodate the limiting rod 35, or it can be a circle that can only accommodate the limiting rod 35. Figure 8 The arrangement of the long strip-shaped hole is shown to facilitate observation during the test whether the running direction of the driving mechanism deviates from the predetermined track.

[0061] In a specific embodiment, Fig.10 As shown, the conical fixing cover 11 is provided with two upper and lower avoidance grooves 111 at the circular hole for inserting the connecting component 3. The setting of the avoidance grooves 111 allows the limiting rod 35 to enter and exit smoothly.

[0062] In a specific embodiment, Figure 7-8 As shown, the two arc-shaped wrapping sheets 311 are respectively provided with a plurality of fixing protrusions 3111 at one end close to the propulsion limiting sleeve 313, and the wrapping sheet sleeve 312 is provided with a fixing groove 3121 matching the fixing protrusion 3111 at the corresponding position, so that the fixing protrusion 3111 is clamped in the fixing groove 3121 to achieve fixation between the arc-shaped wrapping sheet 311 and the wrapping sheet sleeve 312.

[0063] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
