Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a ligator for urological surgery. Background Art

[0002] Male sterilization surgery is to block the output of sperm by cutting the ends of the vas deferens, ligating it, or using electrocoagulation, plugging, chemical drugs, etc. to block the vas deferens to achieve the purpose of contraception. During the ligation operation, the doctor uses his left thumb, index finger and middle finger to fix the vas deferens on the right side of the patient, open the patient's scrotal skin, and push open the spermatic cord blood vessels. Ligation is performed on one side first, and then on the other side. During this process, the doctor is required to use a ligator to fix the vas deferens to prevent it from slipping.

[0003] Most of the ligators currently in use are of a clamp-type structure, which clamps the vas deferens to prevent it from slipping. However, most of the ligators currently in use have a simple structure and are not provided with a corresponding positioning mechanism. They cannot free the user's hands after clamping the vas deferens of different patients, thereby reducing the efficiency of the operation and being inconvenient to use. Utility Model Content

[0004] The utility model aims to provide a ligation device for urological surgery to solve the problems raised in the above background technology.

[0005] In order to achieve the above object, the utility model provides the following technical solutions:

[0006] A urological surgical ligator comprises a first clamp arm and a second clamp arm, wherein the first clamp arm is hinged to the second clamp arm, the first clamp arm and the second clamp arm are commonly connected to a clamp spring, the first clamp arm is connected to a limit plate, the first clamp arm is provided with a mounting groove, the first clamp arm is rotatably connected to a threaded rod, the threaded rod is connected to a toggle disc, the threaded rod is threadedly connected to a resisting square rod, and the resisting square rod resists the limit plate.

[0007] Preferably, both ends of the clamping spring are respectively connected to mounting blocks, the mounting blocks are rotatably connected to a threaded cylinder, the first clamp arm and the second clamp arm are respectively connected to threaded columns, and the threaded cylinder is threadedly connected to the threaded column.

[0008] Preferably, the first clamp arm and the second clamp arm are respectively connected with a silicone pad.

[0009] Preferably, the first clamp arm and the second clamp arm are respectively connected with finger rings.

[0010] Preferably, the interfering square rod is provided with scale lines.

[0011] Compared with the prior art, this technical solution produces the following beneficial effects:

[0012] (1) The technical solution drives the first clamp arm and the second clamp arm to clamp the vas deferens through the clamping spring. The position of the abutting square rod can be adjusted by rotating the threaded rod to control the clamping range of the first clamp arm and the second clamp arm, thereby clamping the vas deferens of different patients to avoid excessive clamping or loose clamping caused by the diameter of the patient's vas deferens being too large or too small. At the same time, the user's hands can be freed. After fixing, the user does not need to continue to apply force on the first clamp arm and the second clamp arm. The user can subsequently free his hands to perform other operations, which greatly improves the efficiency of the operation. Under the condition that the user's hands can be freed, the vas deferens of different sizes can be clamped with appropriate force, and the practicality is greatly enhanced.

[0013] (2) This technical solution can quickly disassemble and assemble the clamping spring through the cooperation of the threaded barrel and the threaded column, and then quickly replace the clamping spring, thereby increasing the subsequent service life of the device; the vas deferens is protected by a silicone pad; the finger ring is convenient for staff to operate and use; the scale line can quickly and accurately adjust the clamping range of the ligator, making it easy to use.

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0021] like Figures 1 to 5The urological surgical ligator shown comprises a first clamp arm 1 and a second clamp arm 3, the first clamp arm 1 and the second clamp arm 3 are hinged to each other to form a scissor-type structure, the first clamp arm 1 and the second clamp arm 3 are commonly connected with a clamp spring 13, the clamp spring 13 is a tension spring, that is, the first clamp arm 1 and the second clamp arm 3 can be pulled to close each other by the clamp spring 13 to complete the clamping of the object, the first clamp arm 1 is connected to a limiting plate 9, the first clamp arm 1 is provided with a mounting groove 5, the first clamp arm 1 is rotatably connected with a threaded rod 8, the threaded rod 8 is connected with a toggle disc 6, the toggle disc 6 is located on the inner side of the mounting groove 5, the threaded rod 8 is threadedly connected with a resisting square rod 7, the resisting square rod 7 is in contact with the limiting plate 9, and the limiting plate 9 can play a role of rotationally limiting the resisting square rod 7, the second clamp arm 3 is in contact with the left end of the resisting square rod 7, and the closing of the first clamp arm 1 and the second clamp arm 3 is limited by the resisting square rod 7, thereby controlling the clamping range.

[0022] The left and right ends of the clamping spring 13 are respectively connected to mounting blocks 12 , the mounting blocks 12 are rotatably connected to threaded cylinders 11 , the first clamp arm 1 and the second clamp arm 3 are respectively connected to threaded columns 10 , and the threaded cylinders 11 are threadedly connected to the threaded columns 10 .

[0023] The first clamp arm 1 and the second clamp arm 3 are respectively connected to a silicone pad 2, and the first clamp arm 1 and the second clamp arm 3 are respectively connected to a finger ring 4. The square rod is provided with a scale line 14, and the clamping range can be accurately adjusted by cooperating with the limit plate 9 to read the reading.

[0024] The threaded rod 8 is rotated by rotating the toggle disc 6, and the limit plate 9 plays a role in limiting the rotation of the abutting square rod 7. Therefore, as the threaded rod 8 rotates, the abutting square rod 7 moves leftward or rightward along the threaded rod 8, thereby limiting the movement of the second clamp arm 3 toward the first clamp arm 1 under the action of the clamping spring 13, thereby completing the adjustment of the clamping width of the ligator.

[0025] The specific implementation process is as follows:

[0026] When using Figure 1Taking the middle view and the right-hand operation as an example, the thumb is inserted into the finger ring 4 of the second clamp arm 3, and the ring finger is inserted into the finger ring 4 of the first clamp arm 1, so that the first clamp arm 1 and the second clamp arm 3 can be opened to each other, so that the upper ends of the first clamp arm 1 and the second clamp arm 3 are also opened. At this time, the spring is further pulled, and then the middle finger pushes the toggle disk 6 to rotate, thereby driving the resistance square rod 7 to move left, and then the vas deferens to be clamped is placed between the two silicone pads 2, and then the hand can stop applying the opening force on the finger ring 4. At this time, under the action of the restoring force of the clamping spring 13, the second clamp arm 3 is driven to close to the first clamp arm 1, and at the same time, the second clamp arm 3 and the upper end of the first clamp arm 1 begin to close until the second clamp arm 3 abuts against the left end of the resistance square rod 7. At this time, the second clamp arm 3 and the upper end of the first clamp arm 1 preliminarily complete the clamping of the vas deferens, and then the toggle disk is pushed in the opposite direction. 6 drives the resisting square rod 7 to move rightward. At this time, under the action of the restoring force of the clamping spring 13, the second clamp arm 3 is driven to move rightward along with the rightward movement of the resisting square rod 7, thereby further completing the clamping of the vas deferens until the clamping force suitable for the vas deferens is adjusted, and the toggle disk 6 can be stopped. At this time, under the action of the clamping spring 13 and the resisting square rod 7, the ligator automatically completes the clamping of the vas deferens. At this time, the doctor can take his finger out of the finger ring 4, and the ligator can be fixed by auxiliary tools or handed over to the auxiliary nurse. The doctor can perform other medical operations after his hands are freed. After use, the second clamp arm 3 and the first clamp arm 1 can be opened directly to release the clamping. The threaded cylinder 11 can be subsequently twisted to complete the disassembly and assembly of the clamping spring 13, which is convenient for quick replacement and avoids the situation where the clamping spring 13 loses its elasticity due to long-term use and affects the clamping.

[0027] The present technical solution drives the first clamp arm 1 and the second clamp arm 3 to clamp the vas deferens through the provided clamping spring 13. The position of the abutting square rod can be adjusted by rotating the threaded rod 8 to control the clamping range of the first clamp arm 1 and the second clamp arm 3, so as to clamp the vas deferens of different patients, thereby avoiding excessive clamping or loose clamping caused by the vas deferens of the patient being too large or too small in diameter. At the same time, the user's hands can be freed. After fixing, the user does not need to continue to apply force on the first clamp arm 1 and the second clamp arm 3. The subsequent user can free both hands to perform other operations, which greatly improves the surgical efficiency and satisfies the situation that the user's hands can be freed. The vas deferens of different sizes can be clamped with appropriate force, and the practicality is greatly enhanced; the clamping spring 13 can be quickly disassembled and assembled through the cooperation of the threaded barrel 11 and the threaded column 10, and then the clamping spring 13 can be quickly replaced, thereby increasing the subsequent service life of the device; the vas deferens is protected by the silicone pad 2; the finger ring 4 is convenient for the staff to operate and use; the clamping range of the ligator can be quickly and accurately adjusted through the scale line 14, which is convenient for use.

[0028] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
