Description

Technical Field

[0001] The present invention relates to the technical field of vasectomy, in particular to a comprehensive surgical clip for improving vasectomy and an operation method thereof. Background Art

[0002] Currently, conventional contraceptive methods include condoms, oral contraceptives, and IUD placement, but these methods all carry the risk of unwanted pregnancy.

[0003] For male sterilization, the vas deferens is usually cut off. However, after the vas deferens is cut off, there is still residual semen in the vas deferens, which can also lead to conception and cannot completely achieve the contraceptive effect.

[0004] Moreover, when performing vasectomy on men, it is inconvenient to fix the vas deferens due to the lack of specific tools, which affects the efficiency of the operation.

[0005] Therefore, we propose a comprehensive surgical clip for improving vasectomy and its operation method. Summary of the Invention

[0006] In response to the shortcomings of the above-mentioned existing production technology, the applicant provides a comprehensive surgical clip for improved vasectomy and an operation method thereof. The special surgical clip is used to improve work efficiency. At the same time, based on the traditional vasectomy surgery, a special flushing technology is added to improve the efficiency of residual semen discharge, which greatly shortens the patient's postoperative contraceptive time compared with traditional surgery.

[0007] The technical solutions adopted in the present invention are as follows:

[0008] A comprehensive surgical clip for improved vasectomy, for vasectomy connected to the epididymis, comprising:

[0009] Comprehensive surgical clips;

[0010] The comprehensive surgical clamp includes two clamps for clamping and fixing the scrotal vas deferens, and the two clamps are connected to the same scissor structure and opened and closed synchronously by the scissor structure;

[0011] Also includes;

[0012] The syringe is tilted and slidably arranged on the integrated surgical clamp and is used to inject the mixed solution into the vas deferens and push the semen out.

[0013] The mixed solution includes two types, one is a combination of physiological saline and methylene blue, and is blue throughout, and the other is vitamin B12 injection, and is red throughout. At the same time, the two mixed solutions appear purple when mixed.

[0014] The clamping head includes two rubber pads arranged opposite to each other, a circular groove for fixing the vas deferens is provided in the middle of the rubber pads, and anti-slip notches for clamping and fixing the soft tissue around the vas deferens are provided on opposite sides of the two rubber pads.

[0015] The scissors structure includes an upper crank, a lower crank, an upper cross bar, a lower cross bar and a knife handle. The upper crank and the lower crank are connected to the chuck, and the two upper cranks and the two lower cranks are connected together through corresponding upper cross bars and lower cross bars, and two cross-arranged knife handles are respectively connected to the side walls of the upper cross bar and the lower cross bar.

[0016] The movable end of the knife handle is connected with a finger ring, and a clamping assembly for accurately controlling the clamping force is connected between the two finger rings.

[0017] The clamp assembly mainly includes an upper clamp and a lower clamp connected to the finger ring, and lower clamp teeth and upper clamp teeth that slightly mesh with each other are respectively provided on the opposite sides of the lower clamp and the upper clamp. A rectangular groove is opened in the upper clamp or the lower clamp, and a compression spring is connected in the rectangular groove along the length direction, and a left guide rod fixed in the rectangular groove is inserted in the compression spring. The movable end of the compression spring is connected to a pointer baffle, and the other side of the pointer baffle is connected to a support rod in the same straight line as the compression spring, and the support rod passes through the rectangular groove and is connected to the lower finger ring or the upper finger ring, and a dial corresponding to the pointer baffle is provided on the end face of the rectangular groove.

[0018] A clamping seat and a syringe seat for fixing the syringe are connected to the side wall of one of the upper cranks.

[0019] The needle of the syringe is directed toward the end of the vas deferens where liquid flows out, the angle between the axis of the syringe and the vas deferens is less than 20°, and a limit block is connected to the outer wall of the syringe to prevent the syringe from excessive displacement.

[0020] A method for operating a vasectomy combined surgical clip comprises the following steps:

[0021] S1: After confirming the location of the vas deferens, the doctor clamps the two ends of the vas deferens with two integrated surgical clips.

[0022] S2: Push two syringes containing different mixed solutions to insert the injection needles of the syringes into the cut vas deferens, and insert the injection needles along the direction of semen discharge;

[0023] S3: After the injection needle is inserted, withdraw the syringe, that is, pull back the piston handle to see if there is any color change. If red blood is found to be sucked in, it means that the insertion position is incorrect and needs to be adjusted;

[0024] S4: If the color of the withdrawn needle is normal, push the piston handle slightly to see if there is resistance or local swelling. If any of the above phenomena occur, it means that the injection needle is inserted into the wrong position and needs to be adjusted.

[0025] S5: If there is no abnormality when pushing the piston handle slightly, inject the mixed solution in the syringe into the vas deferens;

[0026] S6: The vas deferens is cut between the two clamps on the same integrated surgical clamp;

[0027] S7: By observing the color of semen discharged after surgery, the patency of the vas deferens can be determined, providing preoperative evaluation guidance for some patients who need to restore fertility through vasectomy.

[0028] The color of semen discharged has the following situations:

[0029] First, when the semen is red, it means that only the vas deferens on the side where the vitamin B12 injection was injected is unobstructed;

[0030] The second type is when the semen is blue, which means that only the vas deferens on the side of the mixture of saline and methylene blue is unobstructed;

[0031] The third type, when the semen is purple, indicates that both sides of the vas deferens are unobstructed;

[0032] Fourthly, you can also determine the patency of the vas deferens based on the change in semen color. When the semen gradually changes from a single color to purple, it means that one side is not very patency.

[0033] Fifth, when the semen color does not change, it means that the vas deferens on both sides are blocked.

[0034] The beneficial effects of the present invention are as follows:

[0035] The present invention has a compact and reasonable structure and is easy to operate. It improves work efficiency by adopting a special surgical clip. At the same time, it adds a special flushing technology on the basis of traditional vasectomy surgery to improve the efficiency of residual semen discharge, greatly shortening the patient's postoperative contraception time compared with traditional surgery. It can also judge the patency of the vas deferens based on the color of the discharged semen, providing preoperative evaluation guidance for some patients who need to restore fertility and undergo vasectomy, reducing surgical blindness, saving medical resources, and reducing unnecessary pain.

[0036] At the same time, the present invention also has the following advantages:

[0037] (1) The syringe body is tilted and slidably inserted into one of the upper cranks, and the needle of the syringe body is directed toward the end of the vas deferens where the liquid is discharged, so that the mixed liquid pushed out by the syringe body can discharge the residual semen in the vas deferens, thereby flushing the vas deferens and preventing the residual semen from causing an unexpected pregnancy.

[0038] (2) Two mixed solutions are set up, with a mixture of physiological saline and methylene blue injected into one vas deferens and a vitamin B12 injection injected into the other vas deferens. Since the mixed solution is injected towards the semen outlet, the semen in the two vas deferens will mix in the ejaculatory duct. Therefore, as the mixed solution is injected, semen will be discharged. The patency of the vas deferens can be judged based on the color of the semen. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0054] like Figure 1-Figure 7 As shown, this embodiment discloses a comprehensive surgical clip for improving vasectomy, which is mainly composed of a comprehensive surgical clip 2 and a syringe 3, and acts on the vas deferens 101 connected to the epididymis on the testicle 1 to ligate;

[0055] In this embodiment, Figure 4 As shown, the integrated surgical clamp 2 mainly consists of an upper finger ring 201, an upper handle 202, an upper crossbar 203, an upper crank 204, a crank through hole 205, a clamp seat 206, a clamp head 207, a syringe seat 208, a seat hole 209, a lower crank 210, a lower crossbar 211, a lower handle 213, a lower finger ring 214, and a clamp assembly 215;

[0056] In this embodiment, Figure 1 and Figure 3 As shown, there are two clamps 207, and the two clamps 207 are arranged horizontally and respectively clamped on the scrotal section of the vas deferens 101, so as to fix the vas deferens 101 and prevent the vas deferens 101 from sliding and rolling, thereby facilitating the operation;

[0057] like Figure 6 As shown, the chuck 207 includes two rubber pads 20702 arranged opposite to each other, and a circular groove 2703 is provided in the middle of the rubber pad 20702 for placing the vas deferens 101. The circular groove 2703 can position and fix the vas deferens 101 to prevent sliding. In addition, the two rubber pads 20702 are provided with anti-slip grooves 20701 on the opposite sides. The anti-slip grooves 20701 can clamp and fix the soft tissue around the vas deferens 101, thereby further fixing the vas deferens 101. Moreover, since the rubber pad 20702 is made of a relatively soft material, it is not easy to damage the vas deferens 101 and the soft tissue.

[0058] like Figure 4As shown, the upper and lower ends of the chuck 207 are respectively connected to the upper crank 204 and the lower crank 210, and the other ends of the two upper cranks 204 are connected together through the upper cross bar 203. Similarly, the other ends of the two lower cranks 210 are connected together through the lower cross bar 211, and the middle positions of the upper cross bar 203 and the lower cross bar 211 are respectively connected to the cross-arranged upper knife handle 202 and the lower knife handle 213, and the relative movement of the upper and lower knife handles drives the two chucks 207 to clamp the vas deferens 101 at the same time.

[0059] The movable end of the upper handle 202 is connected to the upper finger ring 201 , and the movable end of the lower handle 213 is connected to the lower finger ring 214 ;

[0060] At the same time, a clamping assembly 215 for controlling force is connected between the upper finger ring 201 and the lower finger ring 214.

[0061] like Figure 5 As shown, the clamp assembly 215 mainly includes a lower clamp 21501 connected to the lower finger ring 214 and an upper clamp 21504 connected to the upper finger ring 201. The lower clamp 21501 and the upper clamp 21504 are respectively provided with lower clamp teeth 21502 and upper clamp teeth 21503 that engage with each other on opposite sides. The lower clamp teeth 21502 and the upper clamp teeth 21503 are slightly engaged with each other, providing a sense of frustration without affecting the movement of the lower clamp 21501 and the upper clamp 21504, making it easy to control the force and prevent damage to the vas deferens 101 and soft tissue.

[0062] In addition, a rectangular groove 21505 is provided in the upper clamp 21504 or the lower clamp 21501, and a compression spring 21507 is connected to the rectangular groove 21505 along the length direction, and a left guide rod 21506 fixed in the rectangular groove 21505 is inserted into the compression spring 21507, and the movable end of the compression spring 21507 is connected to the pointer baffle 21509, and the other side of the pointer baffle 21509 is connected to a support rod 21510 which is in the same straight line as the compression spring 21507, and the support rod 21510 passes through the rectangular groove 21505 and is connected to the lower finger ring 214 or the upper finger ring 201, and a dial 21508 corresponding to the pointer baffle 21509 is provided on the end face of the rectangular groove 21505, which can quantify the applied force and cooperate with the clamping teeth to better control the force.

[0063] The syringe 3 mainly includes a syringe body 301, a mixed liquid 302 disposed in the syringe body 301, and a limit block 303 located outside the syringe body 301;

[0064] The syringe body 301 is tilted and slidably inserted into one of the upper cranks 204, and a through hole is provided on the upper crank 204 for convenient insertion of the syringe body 301. A clamp seat 206 and a syringe seat 208 are connected to the side wall of the upper crank 204, and the syringe seat 208 is also provided with a seat hole 209 for convenient insertion of the syringe body 301. At the same time, the needle of the syringe body 301 is directed toward the end where the liquid is discharged from the vas deferens 101, so that the mixed liquid 302 pushed out by the syringe body 301 can discharge the residual semen in the vas deferens 101, preventing accidental pregnancy caused by residual semen, and having the effect of flushing the vas deferens 101.

[0065] The angle r between the axis of syringe body 301 and vas deferens 101 is less than 20°, enabling penetration into vas deferens 101 and imparting a certain amount of force to the semen. This angle is primarily designed to ensure that the needle's penetration into the vas deferens must not be less than 2 mm, ensuring smooth injection of the mixed solution 302 in syringe 3 into the severed vas deferens 101 without damaging the inner wall of the vas deferens due to the sharp needle tip. Given the syringe needle's 0.3 mm diameter and the vas deferens' inner diameter of approximately 1 mm, trigonometric relationships indicate that this angle cannot exceed 20°.

[0066] At the same time, in order to ensure that the needle does not damage the inner wall of the other side of the vas deferens 101, a limit block 303 is connected to the outer wall of the syringe body 301. After the limit block 303 collides with the upper crank 204, it can limit the needle to prevent excessive movement. Since the diameter of the vas deferens 101 in the human body is relatively fixed, the position of the limit block 303 can also be controlled within a reasonable range, so as to better control the accuracy of the needle inserting into the vas deferens 101.

[0067] Example 2

[0068] The difference from Example 1 is that the mixed solution 302 includes two types, one of which is a combination of physiological saline and methylene blue, and is blue throughout;

[0069] The other is vitamin B12 injection, which is red in color. The two mixed solutions 302 will turn purple after fusion. At the same time, the mixture of normal saline and methylene blue and vitamin B12 injection are widely used for injection into the body's blood vessels and are harmless to the body.

[0070] Because there are two vas deferens 101 on the testicle 1, and semen is transported and outputted through the two vas deferens 101 respectively, by setting two mixed solutions 302, a mixture of physiological saline and methylene blue is input into one vas deferens 101, and a vitamin B12 injection is input into the other vas deferens 101. Since the input direction of the mixed solution 302 is toward the semen outlet, the semen in the two vas deferens 101 will be mixed in the ejaculatory duct. Therefore, with the input of the mixed solution 302, semen will be discharged. The discharge conditions are as follows:

[0071] First, when the semen is red, it means that only the vas deferens 101 on the side where the vitamin B12 injection is injected is unobstructed;

[0072] Second, when the semen is blue, it means that only the vas deferens 101 on the side where the mixture of saline and methylene blue is injected is unobstructed;

[0073] The third type, when the semen is purple, indicates that the vas deferens 101 on both sides are unobstructed;

[0074] Fourthly, the patency of the vas deferens 101 can also be determined based on the color change of semen. When the semen gradually changes from a single color to purple, it means that one side is not very patency.

[0075] Fifth, when the semen color does not change, it means that the vas deferens 101 on both sides are blocked.

[0076] After determining the above situation, there are the following benefits in actual use: the relative patency of the vas deferens 101 can be checked, and the speed of semen flowing out of the vas deferens 101 can be compared with the control experimental case, so as to understand the patency of the two vas deferens 101, and provide preoperative evaluation guidance for some patients who need to restore fertility and undergo vasectomy, reduce surgical blindness, save medical resources, and reduce unnecessary pain.

[0077] In addition, because male vasectomy involves disconnecting the vas deferens 101 on both sides at the same time, when the vas deferens 101 needs to be connected after another pregnancy, the normal extent of the vas deferens 101 can be known first, so as to avoid wasting time. Moreover, if the vas deferens 101 is already blocked, treatment can be performed in advance.

[0078] Example 3

[0079] A method for operating a vasectomy combined surgical clip comprises the following steps:

[0080] S1: After determining the position of the vas deferens 101, the doctor clamps and fixes the two ends of the vas deferens 101 with two integrated surgical clamps 2. The vas deferens 101 is placed in the circular groove 2703 to prevent sliding. The doctor then adjusts the clamping force with the clamp assembly 215 to complete the clamping and fixation of the vas deferens 101.

[0081] S2: Push the two syringes 3 containing different mixed solutions 302 so that the injection needles of the syringes 3 are inserted into the cut vas deferens 101 , and the injection needles are inserted along the direction of semen discharge;

[0082] S3: After the injection needle is inserted, withdraw the syringe 3, that is, pull back the piston handle to see if there is any color change. If red blood is found to be sucked in, it means that the insertion position is incorrect and needs to be adjusted;

[0083] S4: If the color of the withdrawn needle is normal, push the piston handle slightly to see if there is resistance or local swelling. If any of the above phenomena occur, it means that the injection needle is inserted into the wrong position and needs to be adjusted.

[0084] S5: If there is no abnormality when the piston handle is pushed slightly, the mixed solution 302 in the syringe 3 is injected into the vas deferens 101;

[0085] S6: cutting off the vas deferens 101 between the two clamps 207 on the same comprehensive surgical clamp 2;

[0086] S7: By observing the color of the semen discharged after the operation, the patency of the vas deferens 101 can be judged. The discharge conditions are as follows:

[0087] First, when the semen is red, it means that only the vas deferens 101 on the side where the vitamin B12 injection is injected is unobstructed;

[0088] Second, when the semen is blue, it means that only the vas deferens 101 on the side where the mixture of saline and methylene blue is injected is unobstructed;

[0089] The third type, when the semen is purple, indicates that the vas deferens 101 on both sides are unobstructed;

[0090] Fourthly, the patency of the vas deferens 101 can also be determined based on the color change of semen. When the semen gradually changes from a single color to purple, it means that one side is not very patency.

[0091] Fifth, when the semen color does not change, it means that the vas deferens 101 on both sides are blocked.

[0092] The present invention has a compact and reasonable structure and is easy to operate. It improves work efficiency by adopting a special surgical clip. At the same time, it adds a special flushing technology on the basis of traditional vasectomy surgery to improve the efficiency of residual semen discharge. Compared with traditional surgery, it greatly shortens the patient's postoperative contraceptive time. It can also judge the patency of the vas deferens 101 according to the color of the discharged semen, and has strong practicality.

[0093] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any modifications may be made within the scope of protection of the present invention.
