Description

Disposable cervical biopsy forceps

Technical field

Technical field of medical instruments is the utility model is related to, specifically a kind of disposable cervical biopsy forceps.

Background technology

Cervix is easily attacked by various malignant bacterias, turns into the multiple position of gynecological disease, in the preventing and treating of cervical disease, Particularly in the generaI investigation of cervix malignant tumour, therapeutic process, the sampling and inspection of uterine neck biological tissue serve important work With, cervical biopsy forceps with its sampling amount is big, biopsy accuracy rate is high and to patient's injury it is small the advantages of obtained in clinic Large-scale use, the lower pliers head of existing disposable cervical biopsy forceps is U-shaped engraved structure on the market, after sampling Sample obscission from the U-shaped engraved structure of lower pliers head be present, so as to cause secondary sample, both added the behaviour of medical worker Make difficulty, and extra pain is caused to patient.

Utility model content

The utility model aims to solve the problem that above mentioned problem, so as to provide one kind avoid produce sampling when sample come off cause it is secondary The disposable cervical biopsy forceps of problem of sampling.

The utility model solves described problem, and the technical scheme of use is：

A kind of disposable cervical biopsy forceps, including upper grip head, lower pliers head, outer tube, left handle, right handles, upper pincers Head and lower pliers head are separately positioned on outer tube one end and are hinged by rotating shaft, and the outer tube other end is connected with right handles, and right handles pass through Rotating shaft is hinged with left handle, and lower pliers head is U-shaped engraved structure, and U-shaped engraved structure is provided with pressure pin.

Using the utility model of above-mentioned technical proposal, compared with prior art, the characteristics of it is protruded, is：

Coming off for sample is effectively prevented, alleviates the operation difficulty of medical worker, avoids secondary sample to patient Extra pain is caused, it is simple in construction, it is practical.

Preferably, the further technical scheme of the utility model is：

Pressure pin and lower pliers head are formed in one structure.

Pressure pin is evenly arranged two, effectively holds the sample of sampling, prevents sample from being come off from the U-shaped mouth of lower pliers head.

Outer tube both sides are provided with scale, solve the problems, such as location difficulty during sampling, effective to improve medical worker's operation Accuracy, shorten sample time, reduce pain of the patient in sampling process.

Embodiment：

With reference to embodiment, the utility model is described in further detail, and purpose, which is only that, more fully understands the utility model Content, therefore, the cited case are not intended to limit the scope of protection of the utility model.

Referring to Fig. 1, Fig. 2, Fig. 3, the present apparatus include upper grip head 1, push rod 3, outer tube 4, right handles 5, spacer 6, cover plate 8, Left handle 11, lower pliers head 13, push rod 3 are connected through outer tube 4 is interior with spacer 6, and spacer 6 is embedded in the locating slot of left handle 11 Interior, the left end of outer tube 4 welds with lower pliers head 13, and the left end of push rod 3 is be hinged by the first rotary shaft 2 and upper grip head 1, the He of upper grip head 1 It is hinged between lower pliers head 13 by the 3rd rotary shaft 12 and then upper grip head 1 can rotates upwardly and downwardly, lower pliers head 13 is engraved to be U-shaped Hollow structure, is provided with two pressure pins being evenly arranged 14 on U-shaped engraved structure, and pressure pin 14 and lower pliers head 13 are formed in one knot Structure, pressure pin 14 effectively hold the sample of sampling, prevent sample from being come off from the U-shaped mouth of lower pliers head 13, the right-hand member of outer tube 4 and the right hand The top of handle 5 is bonded, and scale 15 is carved with the both sides of outer tube 4, and scale 15 is set according to vagina depth, scale value include 6cm, 7cm, 8cm, 9cm, 10cm, 11cm, 12cm, solves the problems, such as location difficulty during sampling, the effective standard for improving medical worker's operation True property, shortens sample time, decreases pain of the patient in sampling process, and left handle 11 and right handles 5 pass through second Rotary shaft 7 is connected, and sets and is provided between left handle 11 and right handles 5 by compression and tension between left handle 11 and right handles 5 Left spring 10 and right spring 9, left spring 10 is in close proximity to left handle 11, and right spring 9 is in close proximity to right handles 5, and cover plate 8 is capped on the right side On the locating slot of handle 5,

The present apparatus can effectively prevent that sample comes off during sampling, avoid producing caused by sample comes off secondary sample and ask Topic, alleviates the operation difficulty of medical worker, avoids secondary sample and extra pain is caused to patient, simple in construction, practical Property is strong.

The preferably feasible embodiment of the utility model is the foregoing is only, not thereby limits to power of the present utility model Sharp scope, all equivalence changes made with the utility model specification and its accompanying drawing content, is both contained in of the present utility model Within interest field.
