DETAILED DESCRIPTION
[0029] The specific implementation of the present application is described in detail below in combination with the drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present application, and is not used to limit the present application.
[0030] As shown in Figures 1 to 6 , it is an exemplary embodiment disclosed by the present application. The pen type elastic thread ligation anastomat comprises a ligation suction head 10, a first ligation pipe body 20, a handle 30 and a ligation assembly 40, the ligation assembly 40 comprises an elastic thread 41 and a push wire pipe 42, the elastic thread 41 passes through the push wire pipe 42, one end of the elastic thread 41 is tied with a slip knot 412 to form a loop 411 with adjustable aperture; the other end of the elastic thread 41 is clamped on the pipe opening of the push wire pipe 42;
[0031] The ligation suction head 10 comprises a guide part 11, a second ligation pipe body 13 and a connecting part 12, the second ligation pipe body 13 is in communication with the guide part 11 and the connecting part 12 respectively, the second ligation pipe body 13 is provided with a first limiting ring 14 near the guide part 11, and the first limiting ring 14 is provided with a plurality of limiting ports 141;
[0032] The first ligation pipe body 20 comprises opposite first and second connecting ends, the first connecting end is in communication with the connecting part 12, the second connecting end is connected with the handle 30, the first ligation pipe body 20 is provided with a sliding block 21 which can move along the axial direction of the pipe body on the outer surface of the pipe body, and the sliding block 21 is provided with a plurality of limiting grooves 211;
[0033] The push tube 42 is fitted into the limiting port 141 and the limiting groove 211, and the ring 411 is fitted onto the guide part 11.
[0034] The ligation suction head 10 of this utility model's pen-grip elastic thread ligation anastomosis device includes a guide portion 11, a second ligation tube 13, and a connecting portion 12. A first limiting ring 14 is provided near the guide portion 11 on the second ligation tube 13, and the first limiting ring 14 has several limiting ports 141. A slider 21 is provided on the first ligation tube 20, and the slider 21 has several limiting grooves 211. The push tube 42 is engaged with the limiting ports 141 and the limiting grooves 211, and the ring 411 is fitted onto the guide portion 11. The push tube 42 is movably connected to the limiting ports 141, and its body is located within the limiting ports 141, but can move left and right. The push tube 42 is fixedly connected to the limiting grooves 211; movement of the slider 21 will cause the push tube 42 to move. One end of the elastic cord 41 has a slipknot 412 forming an adjustable loop 411. The diameter of the slipknot 412 is larger than the diameter of the push tube 42. When the push tube 42 moves, it will move the loop 411. During the operation, the user gently pushes the slider 21 towards the guide part 11. Under the guidance of the guide part 11, the loop 411 automatically contracts due to its own elasticity and is finally placed on the root of the hemorrhoid. Compared with the straight cylindrical suction tube head, the elastic cord 41 loop 411 is tightly fixed to the tube head due to its own elasticity and is not easy to drag. To place the loop 411 on the root of the patient's hemorrhoid, the user often needs to use a complex mechanical mechanism and increase the force to pull or tug. In this way, the mechanical mechanism can easily touch the hemorrhoid tissue, causing greater pain to the patient, and even causing the hemorrhoid root to rupture, making surgery impossible. The ligation suction head 10 of the pen-grip elastic thread ligation anastomosis device of this utility model includes a guide part 11 and a ring 411 disposed on the guide part 11. Under the guidance of the guide part 11, the ring 411 can automatically retract and be fitted onto the root of the patient's hemorrhoids without strong pulling, which can greatly reduce the difficulty of operation for users, avoid the instrument scraping the patient's hemorrhoid tissue, and reduce the patient's pain.
[0035] For example, such as Figure 3 , Figure 4 As shown, in an exemplary embodiment of this disclosure, the guide portion 11 is a hollow frustum, including a first guide end and a second guide end. The second guide end is connected to the second sleeve tube body 13. The first guide end is a free end. The outer diameter of the first guide end is smaller than the outer diameter of the second guide end. The outer surface of the guide portion 11 located between the first guide end and the second guide end is a smooth arc surface.
[0036] The guide portion 11 is a hollow frustum with a cavity connecting the first guide end and the second guide end. The first guide end is a free end used to draw the patient's hemorrhoidal tissue into the cavity of the guide portion 11. The second guide end is connected to the second ligating tube 13 so that the cavity of the guide portion 11 is under negative pressure during operation. During the operation, the ring 411 is first placed on the second guide end of the guide portion 11. After the patient's hemorrhoidal tissue is drawn into the cavity of the guide portion 11, the user gently pushes the slider 21 to move the ring 411. The outer surface of the guide portion 11 between the first and second guide ends is a smooth arc surface, and its outer diameter gradually decreases from the second guide end to the first guide end. When an external force is applied to the ring 411 at the second guide end, the ring 411 will slide and contract along the outer surface of the guide portion 11 from the second guide end to the first guide end under its own elastic force, and finally be placed on the root of the patient's hemorrhoids.
[0037] Furthermore, in an exemplary embodiment of this disclosure, the inner diameter of the first guide end of the guide portion 11 is smaller than the inner diameter of the second guide end, and the inner surface of the guide portion 11 between the first and second guide ends is a smooth arc surface. Thus, the cavity of the guide portion 11 is relatively large at the second guide end and gradually narrows towards the first guide end. When the patient's hemorrhoidal tissue is drawn into the cavity of the guide portion 11, the root of the hemorrhoid is located at the first guide end. Because the inner diameter of the cavity at the first guide end is smaller, the root of the hemorrhoid is compressed and shaped by the guide portion 11, shrinking and compressing it. After the ring 411 slips off the guide portion 11, it can accurately fit over the root of the patient's hemorrhoid.
[0038] For example, such as Figure 1 , Figure 2 As shown, a negative pressure cavity is formed inside the handle 30. One end of the negative pressure cavity is connected to the second connecting end of the first ligating tube 20, and the other end of the negative pressure cavity is provided with a negative pressure interface tube 32, which is connected to the negative pressure device. The handle 30 is provided with a negative pressure release mechanism. In an exemplary embodiment of this disclosure, the negative pressure device generates negative pressure, which acts on the negative pressure cavity inside the handle 30 through the negative pressure interface tube 32. The handle 30 is provided with a negative pressure release mechanism. When the negative pressure release mechanism is closed, the negative pressure cavity generates negative pressure, which acts on the cavity of the guide portion 11 through the first ligating tube 20, allowing the cavity of the guide portion 11 to suck in the patient's hemorrhoidal tissue. When the negative pressure device is closed and the negative pressure release mechanism is opened, the negative pressure in the negative pressure cavity inside the handle 30 is released, and the guide portion 11 releases the hemorrhoidal tissue.
[0039] Specifically, in the example embodiment of the present disclosure, the negative pressure releasing mechanism comprises a negative pressure releasing switch 311, one end of which is hinged to the handle 30, and the other end is naturally raised upward and provided with a sealing boss 312, and the handle 30 is provided with a through hole 313 which is in communication with the negative pressure cavity. When the negative pressure releasing switch 311 is pressed, the sealing boss 312 blocks the through hole 313. The handle 30 is provided with a through hole 313 which is in communication with the negative pressure cavity. When the negative pressure releasing switch 311 is pressed and in a naturally raised state, the through hole 313 connects the negative pressure cavity in the handle 30 with the external air, at this time, the negative pressure cavity cannot generate negative pressure. When the negative pressure releasing switch 311 is pressed, the sealing boss 312 on the negative pressure releasing switch 311 blocks the through hole 313, and the negative pressure generated by the negative pressure device acts on the negative pressure cavity, so that the negative pressure cavity also generates negative pressure.
[0040] For example, one end of the negative pressure cavity is provided with an O-shaped sealing ring 33 at the connection with the second connecting end of the first ligation tube body 20, and / or the other end of the negative pressure cavity is provided with an O-shaped sealing ring 33 at the connection with the negative pressure interface pipe 32. Preferably, as shown in the embodiment, one end of the negative pressure cavity is provided with an O-shaped sealing ring 33 at the connection with the second connecting end of the first ligation tube body 20, and the other end of the negative pressure cavity is provided with an O-shaped sealing ring 33 at the connection with the negative pressure interface pipe 32. Figure 2 For example, one end of the negative pressure cavity is provided with an O-shaped sealing ring 33 at the connection with the second connecting end of the first ligation tube body 20, and / or the other end of the negative pressure cavity is provided with an O-shaped sealing ring 33 at the connection with the negative pressure interface pipe 32. Preferably, as shown in the embodiment, one end of the negative pressure cavity is provided with an O-shaped sealing ring 33 at the connection with the second connecting end of the first ligation tube body 20, and the other end of the negative pressure cavity is provided with an O-shaped sealing ring 33 at the connection with the negative pressure interface pipe 32.
[0041] For example, as shown in the embodiment, the other end of the elastic wire 41 is connected with a pull knob 43 after passing through the push wire pipe 42, and the outer side of the pull knob 43 is provided with a limiting portion 431, and the cross section of the limiting portion 431 is larger than the inner diameter of the pipe opening of the push wire pipe 42. Figure 5 For example, as shown in the embodiment, the other end of the elastic wire 41 is connected with a pull knob 43 after passing through the push wire pipe 42, and the outer side of the pull knob 43 is provided with a limiting portion 431, and the cross section of the limiting portion 431 is larger than the inner diameter of the pipe opening of the push wire pipe 42.
[0042] For example, as shown in the embodiment, the other end of the elastic wire 41 is connected with a pull knob 43 after passing through the push wire pipe 42, and the outer side of the pull knob 43 is provided with a limiting portion 431, and the cross section of the limiting portion 431 is larger than the inner diameter of the pipe opening of the push wire pipe 42. Figure 6As shown, in another exemplary embodiment of the present disclosure, the other end of the elastic line 41 is tied into a dead knot 413 after passing through the push line tube 42, and the diameter of the dead knot 413 is greater than the inner diameter of the tube mouth of the push line tube 42. In this exemplary embodiment, by simply tying the elastic line 41 into a dead knot 413, the diameter of the dead knot 413 is greater than the inner diameter of the tube mouth of the push line tube 42, so as to achieve the purpose of clamping the elastic line 41 to the tube mouth of the push line tube 42, without the need for additional equipment, and the manufacturing is simpler. When the loop 411 is sleeved to the root of the hemorrhoid of the patient, the dead knot 413 can be pulled to tighten the loop 411.
[0043] For example, as shown in the exemplary embodiment of the present disclosure, the utility model pen-gripping elastic line loop ligature anastomat further comprises an elastic line guide part 50, the elastic line guide part 50 is a bullet fluid, and the elastic line guide part 50 is sleeved to the guide part 11. Figure 7 When the loop 411 of the elastic line 41 is sleeved to the guide part 11, it is difficult to directly sleeve due to the small aperture of the loop 411. Therefore, when the loop 411 is sleeved, the elastic line guide part 50 can be first sleeved on the guide part 11, one end of the elastic line guide part 50 is sleeved to the first guide end of the guide part 11, the other end of the elastic line guide part 50 is a sharp head, and the overall shape of the elastic line guide part 50 is similar to the fluid shape of a bullet head. When sleeving, the loop 411 is sleeved to the sharp head of the elastic line guide part 50, and then stretched backward, and the elastic line guide part 50 is removed when the loop 411 reaches the second guide end of the guide part 11. In this way, the loop is more simple and fast to sleeve.
[0044] In summary, the utility model effectively overcomes the various shortcomings in the prior art, and has high industrial utilization value.
