Description

Safety guide for cutting stapler

Technical Field

The utility model relates to a clinical operation assists utensil, concretely relates to safe director for cutting stitching instrument.

Background

The use of the cutting and suturing device greatly shortens the anastomosis time of surgeons in the chest and abdomen operation process. At present, there are many kinds of safety guides for clinical use, such as those used in cardiovascular angiography, and the guidance of surgical instruments makes the operation more accurate and safer. To date, there has been no report on the combined use of a cutting stapler and a safety guide, and it is believed necessary to invent a safety guide suitable for a cutting stapler, both from the viewpoint of surgical safety and accuracy. The cutting and suturing device can cut off the focus and the surrounding tissues in the maximum quantity, but the device cannot be operated blindly in vivo because the device is large in size, inconvenient to move and easy to cause tissue damage. Especially, when the cutting and sewing of organs happen to some important tissues, the cutting and sewing of the organs are always fatal. Therefore, how to reduce the occurrence of accidents is a problem to be solved urgently. If a device is provided which, after passing through an artificially created aperture, would blunt the surrounding tissue and separate the tissue not to be resected, then guide the cutting stapler into the desired position for cutting and stapling, the safety of the procedure would be greatly increased.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a safety guider for a cutting and suturing device, which can be also called as an H-belt for short.

The head end of the safety guider for the cutting suturing device of the utility model is a flat area 101, the middle part is a tissue expansion sacculus 201, and the tail end is a cutting suturing device guide tongue 301; the flat area 101 and the tissue expansion balloon 201 are connected by a guide belt 401; the tissue expansion balloon 201 and the cutting stitching instrument guiding tongue 301 are connected continuously or connected by a guiding belt 401; wherein, a small hole 102 for passing through the deeper tissue or connecting another guide belt is arranged on the flat area 101; the tissue expansion balloon 201 is in a flat rugby shape, and peripheral tissues can be expanded passively through the balloon, so that a cutting stitching instrument can pass through the tissue expansion balloon more conveniently; the cutting stitching instrument guide tongue 301 is in a flat horn shape, and a metal clip at one side of the cutting stitching instrument can directly sleeve the guide tongue 301; the guide strip 401 is elongated and can pass through an artificially created aperture. The ratio of the sum of the lengths of the flat area 101 and the guide belt 401 to the total length of the safety guide is 5-7: 10, and the ratio of the sum of the lengths of the tissue expansion balloon 201 and the guide tongue 301 to the total length of the safety guide is 3-5: 10. The flattened region 101, tissue dilation balloon 201, and guide band 401 are hollow or solid. After the tissue to be cut is guided successfully, the guide tongue is pulled out, and the tissue clamped by the forceps is confirmed to be correct and safe with the aid of the endoscope, so that the tissue can be cut. The whole safety guider has smooth surface and certain elasticity, and can smoothly pass through various tissues. The safety guide is a reusable medical consumable.

The utility model discloses a safe director for cutting stitching instrument is a simple, practical device, can guide cutting stitching instrument cutting through it and sew up the blood vessel, and the bronchus carries out alimentary canal and rebuilds etc.. The "H-band" guide band 401 is slender and can easily pass through the tissue gap, the middle tissue expansion balloon 201 expands the surrounding tissue, the tail end guide tongue 301 with the metal clip can smoothly pass through the tissue gap, the linear cutting stitching instrument is opened, the tissue to be cut is clipped, and then the cutting can be carried out. By means of the device, unnecessary damage to surrounding tissue when it is desired to cut certain tissue for various reasons can be avoided, while the workload of the surgeon can be reduced. The safety guider is a medical consumable material which can be repeatedly used, and has the characteristics of simplicity, practicability and low cost.

Detailed Description

The utility model discloses a safe guide for cutting stitching instrument includes flat region 101, tissue expansion sacculus 201, cuts stitching instrument and draws tongue 301 and bootstrap band 401. As shown in fig. 1, which is an embodiment of the safety guide for a cutting stapler of the present invention, the head end of the safety guide is a flat region 101, the middle is a tissue expansion balloon 201, and the end is a cutting stapler guide tongue 301; the flattened region 101, the tissue dilation balloon 201 and the cutting stapler tongue 301 are all connected by a guide strip 401. The ratio of the sum of the lengths of the flat area 101 and the guide belt 401 to the total length of the safety guide is 7: 10, and the ratio of the sum of the lengths of the tissue expansion balloon and the guide tongue to the total length of the safety guide is 3: 10. Alternatively, as shown in fig. 4, the flattened region 101 and the tissue expansion balloon 201 may be connected by a guide tape 401, while the tissue expansion balloon 201 and the cutting stapler tongue 301 are continuously connected.
