Device capable of preventing samples from remaining in body for laparoscopic surgery

Abstract

The invention discloses a device capable of preventing samples from remaining in the body for laparoscopic surgery. The problems are solved that a myoma rotary cutting machine easily leaves out myomadebris and is difficult to operate. A surgical puncture cannula is matched with an auxiliary puncture cannula, debris can be effectively prevented from falling into the abdominal cavity, and the surgical safety is improved. According to the technical scheme, the device comprises the surgical puncture cannula and the auxiliary puncture cannula which are matched with each other, the surgical puncture cannula comprises a first cannular body, and a clamping ring is arranged at the head end of the first cannular body; a plug which seals a cannular opening of the first cannular body is detachably arranged at the tail end of the first cannular body, a bag body is arranged in the first cannular body, multiple connection ropes are arranged at an opening of the bag body, and the connection ropes extend out of the first cannular body; the auxiliary puncture cannula comprises a second cannular body, an operation handle is arranged at the head end of the second cannular body, and a supporting component which is matched with the bottom of the bag body is arranged at the tail end of the second cannular body.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a device used in laparoscopic surgery to prevent specimens from remaining in the body. Background technique [0002] Uterine fibroids is the most common tumor in the human body, and it is also the most hospitalized disease for a single gynecological disease. Myomectomy is a surgical method to remove fibroids and preserve the uterus. It constitutes the main surgical method for uterine fibroids together with total hysterectomy. It used to be suitable for patients under the age of 40. Compared with total hysterectomy, it It has little impact on sexual life and ovarian function. At present, more and more patients over 40 years old also choose myomectomy. It is one of the diseases with the largest number of inpatient operations in gynecology. Laparoscopic surgery is a minimally invasive surgery method. Generally, there are only 3-4 incisions in the abdomen, and the longes...

AI Technical Summary

Problems solved by technology

Such disadvantages are: (1) every time the fibroids are cut with the myoma rotary cutter, some debris will inevitably drop in the pelvis and abdominal cavity. If the debris is not cleaned up at the end of the operation, these residual parts may Continue to grow (especially for some special types of uterine fibroids such as uterine leiomyoma rich in cells, the growth and proliferation ability is stronger, and it is generally difficult to distinguish this type of fibroids from ordinary types during surgery), which is likely to cause patients Re-sickness will bring secondary pain to the patient, which may also cause patient complaints or even doctor-patient disputes; (2) Every time the rotary cutter cuts the fibroids, the remaining fibroids will become smaller and smaller, and the assistant must choose a new one. The remaining fibroids can only be fixed by clamping, which will increase the difficulty of the operation for both parties and require certain experience and skills. Frequent rotary cutting will damage the assistant's instruments, damage the surgical instruments of both parties and shorten their service life

[0004] To sum up, in the prior art, there is still no effective solution to the problem that the fibroid cutter is easy to miss the fibroid debris and difficult to operate.
