Abstract

The utility model belongs to the field of medical instruments and particularly relates to a laparoscope measuring scale comprising a ruler and a sleeve, wherein the ruler is marked with scales and the sleeve is sheathed outside the ruler. The ruler takes the shape of a thin cylinder, is made from medical rubber and has good toughness, thus being not easy to broken; the sleeve is hollow and cylindrical and made from medical rubber or metal; in addition, the inner surface and the outer surface of the sleeve are smooth, and on the size of the inner diameter, the sleeve can allow the ruler with scales to penetrate through; and the inner side segment of the sleeve has elasticity and can be bent, and the sleeve is not changed on length when being bent. The result of clinical use shows that the laparoscope measuring scale can conveniently measure the distance of any two anatomy positions, and the precise data of the distance can be directly obtained by the ruler with scales, thus overcoming the defects of the prior art.

Description

The peritoneoscope dip stick

Technical field

This utility model belongs to medical instruments field, relates to a kind of laparoscopically measuring device, is specifically related to a kind of peritoneoscope dip stick, and this dip stick can accurately be measured the distance between any two anatomical positions.

Background technology

Laparoscopic technique becomes a main developing direction of surgical field at present, and various related equipments are constantly development and perfect also, but does not see that all the time the measuring device that uses under the suitable peritoneoscope is arranged.Laparoscopically measurement way at present commonly used has following three kinds: a kind of is to measure with epidural catheter, but this conduit is harder, and crisp, fractures easily, measures accurately inadequately, and reading is had any problem under peritoneoscope; Another kind method is the in-vitro measurements method, promptly intravital anatomic points labelling to external, the outer distance of measuring body then, the precision that this method is measured is relatively poor, is subjected to the influence of autologous tissue's distortion easily; Also having a kind of method is with other non-measuring apparatus mark lengths in vivo, and then in-vitro measurements, gauge point is unintelligible on the one hand for this method, is easy to blur, it takes measurement of an angle and is subjected to the obvious effect of perforator position, can not accurately locate the anatomical position of two expections mostly under the situation.

Summary of the invention

The purpose of this utility model is for overcoming the defective of prior art, a kind of laparoscopically measuring device is provided, being specifically related to a kind of peritoneoscope dip stick.When this utility model was measured, a section of described peritoneoscope dip stick was inserted abdominal cavity (to call medial segment in the following text) by special implement, and another section is stayed (to call lateral segment in the following text) outside the abdominal cavity, can directly accurately measure the distance between any two anatomical positions.

Particularly, a kind of peritoneoscope dip stick of the present utility model is characterized in that, it comprises scale (1) and sleeve pipe (2), and described scale is carved with scale on (1), and described sleeve pipe (2) is enclosed within outside the scale (1).

In this utility model, be with graduated scale (1) two ends respectively to be provided with an annular and expand,, be convenient to simultaneously grasp in case it is deviate from sleeve pipe (2).

In this utility model, indicate scale with the lateral segment of graduated scale (1), numerical value is consistent with the length that its medial segment stretches out sleeve pipe (2) part.

In this utility model, be with graduated scale (1) to be carefully cylindrical, adopt medical grade rubber preparation usually, have good toughness, frangibility not, and human body had no side effect.

Described length with graduated scale (1) is 400-1000mm, and diameter is 2-10mm, and this utility model preferred length is 750mm, and diameter is 2mm.

In this utility model, sleeve pipe (2) is hollow, cylindrical, adopts the preparation of medical plastic or metal usually, and its inside and outside two sides is smooth, but internal diameter just the graduated scale of accommodating belt pass through.Sleeve pipe (2) medial segment high resilience can be with being subjected to force direction different and to all directions bending, so that be with graduated scale (1) to be free to slide in sleeve pipe, but the sleeve pipe total length does not change because of its profile.

The length of described sleeve pipe (2) is 300-700mm, and preferred length is 450mm, and its diameter is 3-12mm, and preferred diameter is 5mm.

During use, the medial segment of described peritoneoscope dip stick is inserted the abdominal cavity by special implement, insert the peritoneoscope nipper through another special implement, the annulus of the graduated scale of clamping band (1) medial extremity, and to the abdominal cavity tractive, be placed on predetermined anatomical position, promote sleeve pipe (2) to intraperitoneal then, be with graduated scale (1) to slide to the abdominal cavity together; Sleeve pipe (2) medial extremity is placed another anatomical position, and tighten up graduated scale, the numerical value on the pairing graduated scale of sleeve pipe (2) outboard end this moment is the distance of two anatomical positions.

Through clinical use, the result shows that described peritoneoscope dip stick can be convenient for measuring the distance of any two anatomical positions, and can directly obtain the precise information of this distance by graduated scale, has well overcome the defective of prior art.

For the ease of understanding, this peritoneoscope dip stick is described in detail below by the drawings and specific embodiments.It needs to be noted, specific embodiments and the drawings only are in order to illustrate, obviously those skilled in the art can illustrate according to this paper, and above-mentioned peritoneoscope dip stick is carried out various corrections or change, and these corrections and change also will be included within this utility model scope.
