Wedge-shaped cutting and binding apparatus

Abstract

The invention provides a wedge-shaped cutting and binding apparatus, which comprises a first clamping seat and a second clamping seat which are mutually hinged, a nail bin, a nail anvil and a nail-pushing sheet seat, wherein at least two rows of nail bin holes and a bar-shaped cutter groove are formed on the surface of the nail bin; a group of nail-pushing sheets, a cutter knife and nails are moveably arranged in the nail bin; the surface of the nail anvil is provided with at least one row of nail-forming grooves and a bar-shape anvil correspondingly; the nail-pushing sheets and the cutter are fixed on the nail-pushing sheet seat; the nail-pushing sheet seat is fixed at the front end of the first clamping seat; the nail bin can be relatively and glidingly arranged on the nail-pushing sheet seat; and the nail anvil is fixed at the front end of the second clamping seat. The outer contours of the nail bin, the nail-pushing sheet seat and the nail anvil are wedge-shaped. The wedge-shaped cutting and binding apparatus has the advantage that a wedge-shaped cutting and suturing track can be used for the one-off cutting and suturing formation of tumour tissues on the edge of an organ.

Description

technical field [0001] The invention relates to a novel cutting and binding instrument with a wedge-shaped sewing track, which belongs to the field of medical instruments. Background technique [0002] Cutting and binding instruments are widely used in surgery for wound closure, internal tissue stapling and cutting. Typical cutting and stapling instrument has the suturing part disclosed by U.S. Patent No. 5,275,322 to be a circular tube type cutting stapler, which includes a circular staple bin and anvil. The advantage of this instrument is that the body hemorrhage produced in the operation With the expulsion of the contents, the body tissue is easier to heal after surgery. Before suturing with the above-mentioned circular tubular stapler, the circular tubular tissue needs to be sutured in a purse string. Chinese patent ZL200510123051.4 describes an automatic purse string stapler, which consists of a handle holder and a staple magazine assembly. The two handle holders are ...

Problems solved by technology

However, the current cutting and binding instruments are not suitable for all surgical operations. For example, when performing tumor resection on the edge of the lung, a linear cutting and stapler is generally used to perform two roughly vertical or angled cross cutting and suturing to form a wedge. Incision, but this kind of operation method is not only slightly complicated in the operation procedure; more importantly, the intersection of the two cuts and sutures is easy to cause anastomotic leakage, which is a frequent area of ​​postoperative sequelae and complications, which is harmful to the patient's body. will also have some impact
