Problems solved by technology

[0003] Transversal cutting anastomosis/stapler is often used in open surgery, open surgical field of view is better, but there are disadvantages such as large wounds and slow recovery
The traditional method of laparoscopic surgery is to make three small incisions on the patient's body, each inserting a pipeline-shaped working channel, and all subsequent operations are performed through these three channels; and then the special lengthened surgical instruments are used to complete the surgery under the monitor of the TV, wh

Embodiment Construction

[0038] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0039] Such as Figure 1-17 As shown, the present embodiment provides a transverse endoluminal stapler with a compact structure. The surgical stapler includes an end effector 1, a drive assembly 2, a connecting outer tube 3 and a handle mechanism 4. The drive assembly 2 is used to drive When the end effector 1 performs suturing, the driving assembly 2 is at least partially arranged in the connecting outer tube 3, the end executing device is arranged at one end of the connecting outer tube 4, and the handle mechanism 4 is arranged at the other end of the end effector. The handle mechanism 4 It is connected to the drive assembly 2 in a transmission manner. For details, refer to the connection mode of the drive structure of the stapler in the prior art. By controlling the handl...

Abstract

The invention provides a transverse intracavity stapler with a compact structure. The transverse intracavity stapler comprises an end actuator, a connecting outer pipe and a driving component at leastpart of which is arranged in the connecting outer pipe, wherein the end actuator comprises a staple cartridge shell and a positioning staple; the driving component comprises a driving shell used fordriving the staple cartridge shell; the staple cartridge shell is arranged in a staple cartridge accommodating cavity of the driving shell; an opening is formed in the staple cartridge accommodating cavity, and the staple cartridge shell can be axially arranged along the center shaft of the connecting outer pipe; one end of the positioning staple is arranged in the staple cartridge accommodatingcavity; a positioning staple hole which can be penetrated by the positioning staple, and the other end of the positioning staple is connected with a positioning staple driving mechanism. The structuremounting mode of an existing transverse stapler is improved, the assembly is compact, the radial size of the transverse stapler is effectively reduced, and the transverse stapler can enter an endoscopic surgical channel with a small inner diameter, so that the transverse intracavity stapler can be applied to intracavity surgeries.

Description

technical field [0001] The invention relates to a medical device, in particular to a transverse intracavity stapler with a compact structure. Background technique [0002] The transverse cutting anastomosis / stapler is mainly used for the creation of anastomotic stoma and the closure of the stump or incision in the digestive tract reconstruction and organ resection surgery where it is difficult to expose the surgical field. In the horizontal cutting stapler in the prior art, the positioning pin is set on the staple cartridge, and the longitudinal installation perpendicular to the central axis of the stapler needs to be verified along the staple cartridge during installation, and the installation position of the staple cartridge needs to be additionally provided with a transmission mechanism for connecting with the staple cartridge. The locating needles are docked and matched so that the driving mechanism can drive the locating needles. For example, application number 20151035...
