Description

Guide rail assembly for secondary closing

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to closed guide rail set spare of using of secondary.

Background

The closer is a device used in medicine to replace manual suture, and the main working principle is to use anastomotic nails to perform separation or anastomosis on tissues, similar to a stapler; according to different application ranges, the device can be mainly divided into a skin closer, a digestive tract circular closer, a rectum closer, a circular hemorrhoid closer, a circumcision closer, a blood vessel closer, a hernia closer, a lung cutting and suturing device and the like.

In the aspect of the operation of using the closer to perform the cavity cutting suture and take the separated tissue out of the cavity, the operation comprises a first closing stage and a second closing stage, wherein in the first closing stage, the cavity is sutured by using the staple and forms a channel in the cavity, so that the separated tissue is taken out of the channel formed by the staple, and an operation opening for the separated tissue to pass through is avoided on the body of the patient, so that the wound of the patient in the operation process is reduced; the separated tissue is taken out from the cavity of the patient and then enters a second closing stage, after the cavity is sutured by the staples in the first closing stage, the sutured cavity is divided into two parts, the first staples which are used for suturing on one part of cavity tissue can be matched with the second staples which are used for suturing on the other part of cavity tissue, and then the sutured cavity tissue forming the channel is sutured, so that the second closing operation is realized.

Although the current staples can suture the lumen during use, can be matched with staples on corresponding lumen tissues, and can perform a second closing operation, the inventor finds that the current staples have disadvantages during use, and particularly:

for the matching condition of the first anastomosis nail and the second anastomosis nail used by the closer, a medical worker needs to use a tool to control the first anastomosis nail and the second anastomosis nail so that the first anastomosis nail can be matched with the corresponding second anastomosis nail at the cavity and canal tissue of a patient, but if an auxiliary instrument is inserted into a suturing area in the patient, the medical worker controls the first anastomosis nail and the second anastomosis nail by operating the auxiliary instrument to enable the first anastomosis nail and the second anastomosis nail to be matched with each other, and because a plurality of groups of corresponding first anastomosis nails and second anastomosis nails exist on the cavity and canal of the patient, the matching time and the operation difficulty of the anastomosis nails can be increased by operating the auxiliary instrument of the medical worker, the working efficiency of the medical worker is difficult to improve, and the inserted auxiliary instrument may increase the uncomfortable feeling of the patient.

Therefore, in view of the above problems, it is desirable to design a secondary closing rail assembly for assisting the first staple and the second staple opposite to each other on the lumen tissue to cooperate with each other so as to perform a secondary closing of the lumen when the sutured and channeled lumen is sutured in a closed manner.
