[0002] A tumor stripper is a commonly used tool in gynecological tumor resection surgery. Gynecological tumor surgery includes common vulvar tumors, vaginal tumors, uterine tumors, ovarian tumors, and fallopian tube tumors, with uterine and ovarian tumors being more common.
[0003] The publicly disclosed Chinese patent No. CN215778467U discloses a tumor stripper for gynecological tumor surgery. Through a linkage method, the stripping chuck can be opened and closed, so that the tumor can be stripped. During operation, the stability is good, and during stripping, only by pulling the moving rod can the stripping be carried out, which is more convenient to use, shortens the operation time, thus reducing the pain of patients. Through the set lighting lamp, the light during stripping is better, so the accuracy is higher, reducing the harm to patients and facilitating postoperative rehabilitation. The overall device has a simple structure, is easy to operate and has higher practicability.
[0004] However, the above-mentioned stripper for gynecological tumors still has the following problems in actual use: Although the clamping mechanism at the end of the stripper realizes the clamping and locking of the tumor, such a clamping mechanism cannot be adjusted according to the depth of different tumors during use. Therefore, there are great limitations during the stripping process. At the same time, such a clamping mechanism cannot perform a sleeve lock between the tumor and human tissues. Therefore, after stripping, the wound is exposed, resulting in poor applicability and affecting the stripping efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0027] Please refer to Figures 1 - 5 , the present invention provides the following technical solutions:
[0028] Embodiment 1: To solve the problem that the existing extractor body 1 cannot adjust the use length according to the depth of the tumor, the following technical solutions are elaborated in this embodiment. A gynecological tumor surgical tumor extractor includes an extractor body 1 and an extension slide bar 2 slidably arranged at the left end inside the extractor body 1; a guiding bracket 3 is fixedly arranged at the right end inside the extractor body 1, and the inside of the guiding bracket 3 is threadedly connected to the outer wall of a guiding threaded rod 4.
[0029] The extractor body 1 and the internal extension slide bar 2 are arranged in a concentric structure distribution, and the extractor body 1 and the internal extension slide bar 2 are connected by a clamping method. Moreover, the maximum sliding length of the extension slide bar 2 is less than the length of the guiding threaded rod 4, and the extension slide bar 2 connected by the clamping method cannot rotate inside the extractor body 1.
[0030] As Figure 1 , Figure 3 shown, when it is necessary to adjust the use length of the extractor body 1 according to the depth of the tumor, first, the user holds the right end of the extractor body 1, and then rotates the guiding threaded rod 4 extending out of the right end of the extractor body 1. The guiding bracket 3 threadedly connected to the guiding threaded rod 4 is fixedly installed inside the extractor body 1, so that the rotating guiding threaded rod 4 drives the extension slide bar 2 connected by a bearing at the left end to slide inside the extractor body 1. At the same time, the extractor body 1 and the extension slide bar 2 are connected in a clamping state, so that the extension slide bar 2 will not rotate during the process of driving the extension slide bar 2 to move by rotating the guiding threaded rod 4, thereby adjusting the use length between the extractor body 1 and the extension slide bar 2 for tumors of different depths.
[0031] Embodiment 2: To solve the problem that the existing stripper body 1 cannot be locked onto a tumor during the tumor stripping process, the following technical solution is elaborated in this embodiment. At the central position inside the extension slide rod 2, a partition baffle 5 is fixedly arranged, and at the middle part above the partition baffle 5, a telescopic drive rod 6 is fixedly arranged; among them, the left end of the guiding threaded rod 4 inside the stripper body 1 is connected to the middle part of the right end of the partition baffle 5 inside the extension slide rod 2 through a bearing, and by rotating the guiding threaded rod 4, the extension slide rod 2 is driven to slide inside the stripper body 1; above the left side of the partition baffle 5 inside the extension slide rod 2, a transmission rotating shaft 7 is rotatably arranged through a bearing, and the top end of the transmission rotating shaft 7 and the left end of the telescopic drive rod 6 are meshed and connected with each other through a bevel gear set 8, and a winding roller 9 is fixedly arranged on the outer wall below the transmission rotating shaft 7, and a traction rope 10 is wound around the outer wall of the winding roller 9;
[0032] Both the front and rear ends of the left side of the partition baffle 5 inside the extension slide rod 2 are rotatably connected to the right end of the grasping splint 11 through torsion springs, and the inner sides of the front and rear grasping splints 11 are fixedly connected to the left end of the traction rope 10 on the outer wall of the winding roller 9, and after the winding roller 9 drives the traction rope 10 to wind up, the two grasping splints 11 are clamped together; the right end of the telescopic drive rod 6 of the partition baffle 5 inside the extension slide rod 2 is rotatably arranged above the guiding bracket 3 inside the stripper body 1 through a bearing, and the maximum telescopic length of the telescopic drive rod 6 is greater than the sum of the length of the stripper body 1 and the length of the extension slide rod 2, and by rotating the telescopic drive rod 6 at the right end of the stripper body 1, the grasping splint 11 can be operated to position the tumor;
[0033] A stripping cutting rope 12 is arranged on the bottom surface of the partition baffle 5 inside the extension slide rod 2, and the right end of the stripping cutting rope 12 is arranged below the right end of the stripper body 1 through a main positioning bracket 13, and the left end of the stripping cutting rope 12 is arranged on the bottom surface of the left end of the partition baffle 5 through a secondary positioning bracket 14, and the left end of the stripping cutting rope 12 is in a circular structure for locking and stripping the tumor;
[0034] As Figures 3 - 5 shown, when it is necessary to strip the tumor, first hold the stripper body 1, drive the extension slide rod 2 at its left end and the stripping cutting rope 12 to move above the tumor, and then manually push the right end of the stripping cutting rope 12 to the left. The left end of the stripping cutting rope 12 installed through the main positioning bracket 13 and the secondary positioning bracket 14 gradually expands to reach a range where the tumor can be sleeved. Then, the circular structure at the left end of the stripping cutting rope 12 is sleeved on the tumor and adjusted to the required locking position. Finally, pull the stripping cutting rope 12 at the right end of the stripper body 1 in the opposite direction, so that the left end of the stripping cutting rope 12 gradually shrinks to lock the tumor and the part where it needs to be separated from the human tissue;
[0035] Furthermore, before tumor dissection, it is necessary to limit the position of a part of the tumor through the grasping splints 11 to prevent the problem that it is difficult to take out due to sliding after dissection. Move the front and rear distributed grasping splints 11 to the front and rear sides of the tumor, and then manually rotate the right end of the telescopic drive rod 6, so that it drives the engaged transmission rotating shaft 7 and the winding roller 9 to rotate through the bevel gear set 8. The wound traction rope 10 drives the left end thereof to tighten, and at the same time, the grasping splint 11 fixedly connected to the left end of the traction rope 10 turns inward to grasp the tumor, so that the tumor releases the dissection cutting rope 12 after dissection, and the grasped tumor is taken out of the body by the grasping splint 11.
[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
