Abstract
The utility model provides a lifting mechanism of a disposable endoscope sheath. The lifting mechanism comprises a lifting mechanism body which comprises a first lifting component and a second lifting component, and the first lifting component is movably connected with the second lifting component. The first lifting component is provided with a first mounting hole. The second lifting component is provided with a second mounting hole. The lifting mechanism of the disposable endoscope sheath has the advantages that the lifting mechanism body formed by the first lifting component and the second lifting component which are movably connected with each other is arranged at the front end of a disposable cystoscope sheath and located between the disposable cystoscope sheath and the head of a pair of biopsy forceps. Moreover, a pull thread of the disposable cystoscope sheath penetrates through the first mounting hole and the second mounting hole and is connected with a pull thread adjusting ring.
Description
Technical field
This utility model relates to medical instruments field, especially relates to lifting mechanism in a kind of disposable endoscope mirror sheath.
Background technology
At medical field, such as urology department, related parts of human body inside is checked or during Minimally Invasive Surgery, the mirror sheath is the most frequently used endoscope's adnexa.For protection endoscope check and operation in not contaminated, avoid cross infection, for reducing the adverse effect that causes because of repeated multiple times sterilization, endoscope performance, clinical middle disposable endoscope sheath is used more and more extensive simultaneously.When operation is got active somatic cell and done inspection, generally get cell sample by getting biopsy forceps.In practical operation, get the bad control of angle of biopsy forceps, be difficult to find the only biopsy angle of getting.For addressing this problem, design and a kind ofly can realize that the mechanism of the angular adjustment of biopsy forceps is imperative.
Summary of the invention
Problem to be solved in the utility model provides lifting mechanism in a kind of disposable endoscope mirror sheath, especially is fit to the operating theater instruments of needs adjusting angle.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: lifting mechanism in the disposable endoscope mirror sheath comprises the lifting mechanism body; Described lifting mechanism body comprises that first of flexible connection lifts parts and second and lift parts; Described first lifts parts is provided with the first installing hole, and described second lifts parts is provided with the second installing hole.Described first to lift parts be that an end is arc, and the other end has flat side's bar on a slope; Described second to lift parts be that an end is arc, and the other end has flat side's bar on a slope; And lift parts and be connected the slope one end connection of lifting parts first.
Further, described the first installing hole is provided with breach.
Further, described lifting mechanism body is plastic body.
Further, described first lift the thickness that parts and second lift the junction of parts and lift the thickness that parts and second lift parts less than first.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, first lift parts and second and lift the front end that lifting mechanism body that parts form is installed on disposable cystoscope sheath by what be flexibly connected, and at disposable cystoscope sheath and get between the head of biopsy forceps, and the wire drawing of disposable cystoscope sheath is passed the first installing hole and is connected installing hole and connects the wire drawing adjustment ring.After getting biopsy forceps and inserting mirror sheath instrument channel, until be inserted into the degree of depth that needs, by the pulling of wire drawing adjustment ring, so that lift contraction, and the head of getting simultaneously biopsy forceps reaches with the contraction of lifting mechanism and regulates the purpose of getting the biopsy forceps angle.Convenient; Have simple in structure, modern design, processing cost is low, is convenient to the advantages such as control.

Fig. 1 is the front sketch map that stretches that lifts of the present utility model;
Fig. 2 is that this utility model lifts the rear sketch map that stretches;
Fig. 3 is that this utility model duty is lifted and lifted front sketch map.
Among the figure:
1-1, the first installing hole 1-2, the second installing hole 2, lifting mechanism body
2-1, first lifts parts 2-2, second and lifts parts 3, gets the biopsy forceps head
4, mirror sheath 5, wire drawing adjustment ring 6, get biopsy forceps
The specific embodiment
As shown in Figures 1 to 3, this utility model provides lifting mechanism in a kind of disposable endoscope mirror sheath, comprises lifting mechanism body 2; Described lifting mechanism body 2 comprises that first of flexible connection lifts parts 2-1 and second and lift parts 2-2; Described first lifts parts 2-1 is provided with the first installing hole 1-1, and described second lifts parts 2-2 is provided with the second installing hole 1-2.Described first lifts parts 2-1 and second lifts being uneven in length of parts 2-2.The first length of lifting parts 2-1 is greater than the second length of lifting parts 2-2.Described the first installing hole 1-1 is provided with breach.Described lifting mechanism body 2 is plastic bodies.Described first lifts the thickness that parts 2-1 and second lifts the junction of parts 2-2 lifts the thickness that parts 2-1 and second lifts parts 2-2 less than first.
The work process of this example: lifting mechanism body 2 is installed on the front end of disposable cystoscope sheath, and at disposable cystoscope sheath and get between the biopsy forceps head 3, and the wire drawing of disposable cystoscope sheath is passed the first installing hole 1-1 and is connected installing hole 1-2 and connects wire drawing adjustment ring 5.Insert the instrument channel of mirror sheaths 4 when getting biopsy forceps 6, until when being inserted into the degree of depth that needs, by 5 pullings of wire drawing adjustment ring, so that lifting mechanism shrinks, and getting simultaneously biopsy forceps head 3 and reach with the contraction of lifting mechanism and regulate the purpose of getting biopsy forceps 6 angles.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to this utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
