Vaginal incision locator

Abstract

The vaginal cutting positioner of the present invention comprises a positioning cup, an operating rod and a handle, wherein the handle is at the proximal end of the operating rod, and the positioning cup is at the distal end of the operating rod. The operating rod can manipulate the positioning cup to place the positioning cup deep into the vagina. After the positioning cup is placed into the vagina, the vagina can be stretched open to provide support for the vaginal cutting process. At the same time, the end of the positioning cup can form a positioning end to position the vaginal cutting part. During clinical use, the surgical instrument can easily cut the vagina along the end of the positioning cup, and the clinical use process is very convenient.

Description

Technical Field

[0001] The invention relates to a medical device, in particular to a vaginal cutting positioner used in the vaginal cutting process during hysterectomy. Background Art

[0002] With the development of laparoscopic technology, more and more surgeries are performed under laparoscopy, including a large number of malignant tumor surgeries, including total hysterectomy for cervical cancer.

[0003] When performing cervical cancer surgery using laparoscopy, due to the flow of carbon dioxide gas that creates pneumoperitoneum pressure, if cervical cancer tissue or cancer cells leak, it is easy to cause cancer cells to be seeded in the abdominal cavity. The existing technology has no effective solution to this problem, so open surgery is clinically recommended to avoid the seeding of cancer cells in the abdominal cavity with the flow of carbon dioxide gas.

[0004] To solve the above problems, the applicant disclosed a tying device in the patent "Cervical ostium tying device for total hysterectomy", which can tie the vaginal part of the cervix to completely close the vagina in front of the cervix, thereby completely preventing the spread of cancer cells, and then cut the vagina to safely remove the removed diseased uterus from the body. However, in clinical operations, since the vagina is a soft tissue that collapses naturally, the process of cutting the vagina is often difficult because there is no fulcrum.

[0005] The purpose of the present invention is to solve the problem that there is no fulcrum during vaginal cutting and cutting is difficult, and to develop a vaginal cutting positioner. Summary of the invention

[0006] The vaginal cutting positioner of the present invention first uses the positioning cup to open the vagina before vaginal cutting, and then uses the surgical instrument to cut the vagina along the positioning groove at the end of the positioning cup. Due to the supporting and positioning function of the positioning cup, the surgical process can be completed very conveniently.

[0007] The vaginal cutting positioner of the present invention is characterized in that: the vaginal cutting positioner 100 comprises a positioning cup 1, an operating rod 2 and a handle 3; the handle 3 is at the proximal end of the operating rod 2, and the positioning cup 1 is at the distal end of the operating rod 2.

[0008] The operating rod 2 can manipulate the positioning cup 1 and place the positioning cup 1 deep into the vagina 4. The positioning cup 1 can support and position the vagina 4. During surgery, the positioning cup 1 of the vaginal cutting locator 100 is first placed into the vagina 4 to stretch the vagina 4, and then the vagina 4 is cut along the end of the positioning cup 1 using a surgical instrument 6 such as an electric knife or an ultrasonic knife. The end of the positioning cup 1 can play a good positioning role. Since the positioning cup 1 can be fixed in the vagina 4, the surgical instrument 6 can obtain good support during the cutting process, and the vagina 4 cutting process is very convenient.

[0009] The positioning cup 1 is provided with a cutting positioning groove 11. The cutting positioning groove 11 is usually arranged at the front end of the positioning cup 1. The cutting positioning groove 11 can be a positioning groove of various shapes such as an arc positioning groove 11-1, an annular positioning groove 11-2, etc. The applicant does not give examples one by one here, but they all do not depart from the protection scope of this application.

[0010] The positioning cup 1 is detachably connected to the distal end of the operating rod 2. The detachable connection mode can conveniently remove the positioning cup 1 from the operating rod 2, which is convenient for cleaning and can replace the positioning cup 1 of different shapes and sizes as needed. The positioning cup 1 can be detachably connected to the distal end of the operating rod 2 by means of threaded connection, concave-convex card fit, interference fit, etc.

[0011] The proximal end of the positioning cup 1 is provided with a guide rib 12. The guide rib 12 can play a guiding role when the vaginal cutting positioner 100 is withdrawn from the vagina 4, so that the withdrawal is smoother.

[0012] The distal end of the positioning cup 1 is a blunt-tip structure. The blunt-tip design can ensure that the positioning cup 1 does not cause accidental damage to the vaginal tissue during the insertion of the positioning cup 1 into the vagina. The distal end of the positioning cup 1 can usually be designed into a circular, arc-shaped, conical, bullet-shaped, etc. structure, which makes it easier for the positioning cup 1 to enter the vagina.

[0013] The operating rod 2 is provided with a scale 21. The scale 21 can intuitively display the depth of the positioning cup 1 entering the vagina 4.

[0014] The positioning cup 1 is provided with a mark 13. The mark 13 on the positioning cup 1 can identify the size of the positioning cup 1. During clinical use, the positioning cup 1 of different sizes can be selected as needed, which is more convenient for clinical use.

[0015] During clinical use, the uterus is first freed, and then the upper segment of the vagina 4 is tied tightly with the ligation device 5. Then, the operating rod 2 is operated to insert the positioning cup 1 deep into the vagina close to the tied upper segment of the vagina. Then, the surgical instrument 6 is used to cut the vagina 4 along the outer side of the positioning cup 1. The vaginal cutting positioner 100 is withdrawn, and the removed uterus is taken out through the vagina 4. Then, the cut end of the vagina 4 is sutured.

[0016] The vaginal cutting positioner of the present invention comprises a positioning cup 1, an operating rod 2 and a handle 3, wherein the handle 3 is at the proximal end of the operating rod 2 and the positioning cup 1 is at the distal end of the operating rod 2. After the positioning cup 1 is inserted into the vagina, it can stretch the vagina and provide support for the vaginal cutting process. At the same time, the end of the positioning cup 1 can form a positioning end to position the vaginal cutting part. When used clinically, the surgical instrument 6 can easily cut the vagina along the end of the positioning cup 1, and the clinical use process is very convenient. BRIEF DESCRIPTION OF THE DRAWINGS
