Description

Clinical department of internal medicine vessel forceps

Technical field:

The utility model belongs to internal medicine clinical treatment equipment technology field, and in particular to a kind of clinical department of internal medicine vessel forceps.

Background technique:

Vessel forceps are mainly used for clamp blood vessel or blutpunkte, play separation anatomical tissue, clamp skin, internal organs, Tissue Blood The effect of pipe.Currently, usually used vessel forceps are mainly by plier, articulated shaft, pincers clinically there are many kinds of the vessel forceps of class Arm, locating rack and finger ring circle are constituted, and are mainly used to ligature blood vessel, and in the course of surgery, ligature past contact needs pair after blood vessel Edge of a knife position is expanded by stretching pliers, to observe lesions position, and dialysis blood vessel is generally required after ligaturing blood vessel, in order to perform the operation Operation, this just needs to operate cumbersome, time-consuming and laborious again with scalpel or operating scissors come dialysis, increases to medical worker Great work difficulty is added, when carrying out internal medicine deep operation, often due to light reason, can not provide good for doctor The visual field influences operation progress；Therefore, the vessel forceps of the prior art are unable to satisfy use demand, need to improve.In addition, existing There is the binding clip of haemostatic clamp to be mainly used for clamping vascular site, two pliers easy lateral sliding in clamping process causes clamping unstable The case where, and when haemostatic clamp clamps blutpunkte, also have watery blood outflow, it is necessary to be aspirated by other aspirators, efficiency Low, effect is poor.

Utility model content:

For existing haemostatic clamp generally existing defect and deficiency, the utility model provides a kind of clinical department of internal medicine vessel forceps, While controlling two interior plier opening and closing by tong arm to realize, additionally it is possible to control the closure of two outer pliers and open It opens, the musculature of blood vessel two sides is unfolded by outer plier in outer plier and interior plier counter motion, to be conducive to clinical treatment The purpose of operation.

Solution adopted by the utility model to solve its technical problems is that: a kind of clinical department of internal medicine vessel forceps, including in two The front end of plier, two tong arms connecting respectively with two interior pliers is hinged by articulated shaft, two tong arm ends point Not She Zhi finger ring circle and shaping rack, outer clamp handle is respectively fixed on the outside of described two tong arms, the end of each outer clamp handle is divided It is not provided with outer plier；The integral structure of the outer plier and outer clamp handle group camber or broken line type, the integral structure Be fixed together on the outside of tong arm or the integral structure and tong arm on the outside of to pass through pin shaft one hinged, and clamp outside Regulating mechanism one is provided between handle and tong arm；Or hinged by pin shaft two between outer plier and outer clamp handle, outer pincers It is fixed together on the outside of handle and tong arm, regulating mechanism two is provided between outer plier and outer clamp handle.

The regulating mechanism is first is that be connected with lateral tension spring, while the spiral shell in outer clamp handle between on the outside of the outer clamp handle and tong arm For line through adjusting jackscrew is equipped with, the inner end for adjusting jackscrew is supported on tong arm lateral surface；Alternatively, the regulating mechanism is first is that clamping It is provided with card slot on the outside of arm and width of rebate is less than slot bottom width, screw thread, which runs through, in outer clamp handle is equipped with adjusting screw, the tune The inner end for saving screw has block machine, which, which is located in the card slot, will not fall off.

The regulating mechanism on the outside of outer clamp handle and tong arm second is that be respectively arranged with activity traction button and fixed traction button, often A traction, which is buckled, is connected separately with screw rod, and the hand of spiral of two screw rods is on the contrary, two screw rods are connected to the both ends for adjusting screwed pipe simultaneously； Alternatively, regulating mechanism draws button and fixed traction button second is that being respectively arranged with activity on the outside of outer clamp handle and tong arm, screwed pipe is adjusted Both ends be connected separately with two screw rods, the hand of spiral of two screw rods is on the contrary, the end of one of screw rod and a traction button company It connects, is connected with longitudinal tension spring between the end of another screw rod and another traction button.

The middle inside of each interior plier is provided with hemostatic cotton card slot.

The utility model has the beneficial effects that the utility model can control two interior plier opening and closing by tong arm Simultaneously, additionally it is possible to control the closure and opening of two outer pliers.When interior plier opens, that is, when starting to clamp blood vessel, Outer plier is fitted in the lateral surface of interior plier, and the aperture of interior plier is maximum at this time, and the aperture of outer plier is minimum, is convenient for and organizes wound Mouth combines.After manipulating tong arm makes interior plier start closure, outer plier is unfolded to a certain degree outward instead, at this point, by making up tong Mouth makes wound vessel sealing, and the musculature of blood vessel two sides is unfolded by outer plier, operates to be conducive to clinical treatment.

The utility model can also reach by adjusting the distance between outer plier and tong arm and control outer plier expansion in advance With the purpose of closure degree, to keep the expansion control of outer plier more flexible practical.
