Embodiment 1

[0046] Such as figure 1 As shown, this embodiment provides a surgical instrument for resection of uterine cancerous vaginal canal, specifically including a strap 1 (this embodiment uses a spring as a strap, or a special spring-crack ring as a strap, Since the slap ring has two stable states after special molding treatment, namely strip shape and curl shape, it is convenient to wrap around the outer wall of the vaginal canal through clamp operation in the narrow abdominal cavity), shaft tube 2, expansion unit 3 and cutting unit 4;

[0047] Bandage 1, the bandage 1 has a connecting piece that connects the two ends of the bandage 1, and is used to wrap around the outer wall of the vaginal canal during the operation;

[0048] The expansion unit 3, which is sleeved on the shaft tube 2 and located between the inner end surface of the shaft tube 2 and the cutting unit 4, is used for placing in the inner cavity of the vaginal canal during the operation, and passing through the The e...

Embodiment 2

[0057] On the basis of Example 1, preferably, a kind of uterine cancerous vaginal canal resection surgical instrument provided in this embodiment, considering the uneven thickness of the vaginal canal, is more laborious in the actual knife cutting process, wherein the blade 11 is Electric knife or electric cutting machine, at this time, the outer end of the spring leaf stops at the outer end surface of the expansion unit, and does not contact the spring leaf during the cutting process of the electric knife or cutting machine, so as not to hinder the cutting process.

[0058] The working process and principle are as follows: when the expansion piece 6 presses the corresponding vaginal canal wall and makes it closely fit on the inner ring surface of the bandage 1, stop pumping air, and drive the circular cutting machine to move through the overhanging structure 10 until the cutting piece is in contact with the vaginal canal wall. When the tube wall is in contact, the cutting piec...

Embodiment 3

[0060] Preferably, on the basis of Example 1, such as Figure 11 and Figure 12 As shown, considering the accuracy requirements and sealing performance of the expansion, the expansion chute structure 19 with high expansion precision and the annular partition 20 specially added for axial sealing are used in this embodiment to replace the air bag in Embodiment 1. The expansion block combination structure, wherein the expansion unit 3 includes an annular partition 20 and an expansion chute structure 19, the expansion chute structure 19 is sleeved on the shaft tube 2, and the annular partition 20 is set set on the shaft tube 2 and on the inner end surface of the expansion chute structure 19;

[0061]Also in consideration of the cutting precision requirements, the overhanging structure 10 in the cutting unit 4 is also replaced with an expanding chute structure 19 .

[0062] The expansion chute structure 19 in this embodiment is a prior art, and will not be described in detail her...

Abstract

The invention discloses a uterine cancer vaginal canal resection operation instrument, belonging to the technical field of medical instruments. The uterine cancer vaginal canal resection operation instrument specifically comprises a fixing unit and a cutting unit. A vaginal inner circumcision type is proposed for the first time, and the vaginal canal is fixed on the inner wall of the vaginal canal. On the one hand, the vaginal canal has closed the uterus before resection; on the other hand, the uterus to be resected is prefixed on a device and can be directly pulled and moved out by the deviceafter the resection operation is completed without additionally placing a forceps clip for clamping and traction, the process is simple and reliable, and the possibility of cancer cells falling is eliminated fundamentally. In addition, the resection operation is directly completed in the vaginal canal, which is different from a traditional mode of resection from the outer wall of the vaginal canal, and the operation convenience is clear at a glance.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a special surgical appliance for excision of the vaginal canal due to uterine cancer. Background technique [0002] Cervical cancer is currently the disease with the highest incidence rate among gynecological malignancies in my country. The vast majority of cervical cancers are found in stage I and stage II, and surgery is the main treatment for this stage. In the past 20 years, laparoscopic surgery (including traditional laparoscopy and robot-assisted laparoscopy) has gradually replaced open surgery and has become the dominant surgical method due to its advantages of precision, safety, fast recovery, and short hospital stay. However, in 2018, two very important studies found that the recurrence and survival rate of laparoscopic surgery was significantly lower than that of open surgery, which caused an uproar in the international obstetrics and gynecology field. After ...
