Description

Puncture instrument for anus ring shrinkage

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a puncture instrument for anus ring shrinkage.

Background

Rectal prolapse, commonly known as "rectocele," refers to a common anorectal disease in which the mucosa of the rectal and anal canal is everted and emerges outside the anus. Repeated prolapse over time can cause damage to the pudendal nerve and result in anal incontinence, and even complications such as bleeding, edema, incarceration and necrosis. Rectal prolapse is mainly treated by operation, has various operation modes and no international unified standard, and has more postoperative complications and sequelae and high recurrence rate.

The purpose of the rectal prolapse operation is to solve the problems of prolapse, anal looseness and anal defecation control. The Delorme operation is an operation mode which is early and wide in clinical application, the prolapsed mucous membrane is stripped, the muscular layer is folded, the mucous membrane layer is anastomosed again, foreign related documents report that the recurrence rate is 10% -15%, the incidence rate of early complications such as postoperative infection, hemorrhage, urine retention and the like is about 4% -12%, and the prolapse mucous membrane is only cut off, the muscular layer is folded, so that the injury to ligaments and muscles is small, the anal incontinence can not be caused after the operation, but the postoperative patient often has symptoms of tenesmus. The Delorme operation should be selected as appropriate indication in clinical application, and is improved according to the specific situation of a patient in practical application to form an improved Delorme operation so as to reduce the incidence rate of postoperative complications. In recent years, various treatment methods related to rectal prolapse emerge clinically, and representative methods include transperineal rectocele resection and rectal mucosectomy myofascial fold surgery (Altemeier surgery), PPH combined rectal mucosal columnar suture and ligation, hemorrhoid-eliminating injection and the like.

However, the above operation method is too difficult to be performed in most primary hospitals, and is not conducive to the development of the rectal prolapse operation, so that physicians begin to try to use an operation method with low risk, easy operation and a good curative effect, and practice shows that the postoperative recurrence rate of patients with primary rectal prolapse can be reduced to 14% by using "anal ring retraction and trans-anal rectal mucosa suture, and compared with the above other operation methods, the recurrence rate is low and easy to be performed, and the technical bottleneck of the operation method is lack of a proper puncture tool.

Traditionally, there is no special instrument for the anus ring contraction, and most doctors use a curved vessel forceps, an aneurysm needle, a large curved round needle or a long puncture needle curved into a semicircle to insert from the rear incision, pass through the subcutaneous tissue on the outer edge of the sphincter at one side of the anus, and penetrate out from the front incision. However, the conventional instruments have the following disadvantages: the diameter of the puncture needle of the curved vessel forceps is 5mm, the sphincter is easy to be damaged due to too large diameter, and the aneurysm needle, the large curved round needle or the long puncture needle is not easy to operate due to no handle, so that the effect of the anus ring constriction is poor.

Therefore, how to provide a puncture instrument for the anus ring art that contracts realizes reducing the operation degree of difficulty of anus ring art that contracts, reduces the damage of sphincter, and then promotes operation quality, becomes a technical problem that awaits solution urgently.

Disclosure of Invention

The to-be-solved technical problem of the utility model lies in providing a puncture apparatus for anus ring contracts art, realizes reducing the operation degree of difficulty that the anus ring contracted the art, reduces the damage of sphincter, and then promotes the operation quality.

The utility model discloses a realize like this: a puncture instrument for anus ring shrinkage comprises a semicircular puncture needle and a handle; one end of the puncture needle is provided with a needle hole for threading a silk thread, and the other end of the puncture needle is fixedly connected with the handle; the diameter of the puncture needle is less than 3 mm; the end of the puncture needle provided with the needle hole is of a blunt structure.

Further, the handle is perpendicular to the tangent of the puncture needle.

Furthermore, the lateral wall of handle is equipped with the plural number antiskid line.

The utility model has the advantages that:

compared with the traditional curved vessel forceps, the diameter of the puncture needle is smaller than 3mm, so that the sphincter is not easy to be damaged during the anus ring shrinkage operation; compared with the traditional aneurysm needle, large-bending round needle or long puncture needle, the handle is convenient for operating the puncture needle to puncture the needle in the anus ring shrinkage operation, so that the operation difficulty of the anus ring shrinkage operation is reduced; the puncture needle is designed into a semicircle shape and is matched with the shape of the anus, so that the threading of the silk thread around the anus is facilitated; through inciting somebody to action the pjncture needle is equipped with the one end of pinhole and establishes to blunt nature structure, makes difficult damage surrounding tissue when the pjncture needle punctures, very big reduction the operation degree of difficulty of anus ring contract art promptly, reduce the damage of sphincter, and then very big promotion operation quality.

Drawings

The invention will be further described with reference to the following examples with reference to the accompanying drawings.

Fig. 1 is a schematic structural view of a puncture instrument for anus ring contraction of the present invention.

Fig. 2 is a schematic view of the application of the puncture instrument for the anus ring contraction.

Description of the labeling:

100-a puncture instrument for anus ring shrinkage, 1-a puncture needle, 2-a handle, 11-a needle hole, 21-anti-slip lines, 3-silk threads.

Detailed Description

The embodiment of the utility model provides a through providing a puncture apparatus 100 that is used for anus ring to contract art, solved among the prior art anus ring and contracted the art and do not have special instrument, lead to the operation degree of difficulty high, damage the technical problem of sphincter easily, realized very big reduction the operation degree of difficulty of anus ring contract art, reduce the damage of sphincter, and then very big promotion the technological effect of operation quality.

The embodiment of the utility model provides an in technical scheme for solving above-mentioned problem, the general thinking is as follows: the operation difficulty of the anus ring shrinkage operation is reduced by arranging the handle 2; the diameter of the puncture needle 1 is set to be less than 3mm, and the puncture end is of a blunt structure, so that damage to the sphincter during operation is reduced.
