Description

A kind of percutaneous passage stretching pliers

Technical field

This utility model relates to medical instrument field, is specifically related to a kind of percutaneous passage stretching pliers.

Background technology

Clinical medicine needs often carry out percutaneous passage expansion, to carry out Application of Laparoscopy In The Retroperitoneum, through abdominal cavity laparoscopic surgery and thoracoscopic operation etc.

The stretching pliers that existing surgical clinical uses mainly contains two kinds: straight shape vascular forceps and bending vascular forceps.Surgeon can utilize these two kinds of stretching plierses to carry out passivity tissue expander, thus expansion percutaneous passage.When adopting above-mentioned two kinds of stretching plierses, first use pincers spine to enter the subcutaneous of otch, then strutting subcutaneous tissue, is to meet instructions for use when needing the degree of depth of expansion more shallow.But when needing the degree of depth of expansion darker, often need pincers to hold up to operate, the hands that at this moment operator holds clamp handle needs to be suspended on higher the top of access incisions, such difficulty increasing operation, uses comparatively inconvenience.And the hand of operator easily blocks access incisions superjacent air space, make the situation that operator is difficult to by eye observation passageways dilate position.

Being not difficult to find out, also there is certain defect in prior art.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of percutaneous passage stretching pliers, is convenient to carry out percutaneous passage expansion.

For achieving the above object, this utility model is by the following technical solutions:

A kind of percutaneous passage stretching pliers, comprise two symmetrical configuration calipers, caliper comprises handle portion, articulated section and working end; Handle part is in the rear end of caliper, and the end of handle portion is in the hollow and annular matched with human finger; Hinge point is in the middle part of caliper, and two calipers adopt pin hinged through articulated section; Working end is positioned at the front end of caliper, and working end is at right angles arranged relative to handle portion, and working end is in the taper most advanced and sophisticated tapering, root is thick.

Further, the working end length of described caliper is 3-10 centimetre.

A kind of percutaneous passage stretching pliers that this utility model provides, has the following advantages:

Working end is at right angles arranged, and the hand carrying out operator during percutaneous passage expansion does not need unsettled lifting, more convenient operation;

The hand of operator can not block the sight line of access incisions, and handled easily person observe;

Reduce operation easier, the damage to patient during minimizing clinical tasks.

Accompanying drawing explanation

In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Detailed description of the invention

For making the object of this utility model embodiment, technical scheme and advantage clearly, below in conjunction with this utility model embodiment and accompanying drawing, the technical scheme in this utility model embodiment is clearly and completely described.It should be noted that, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.

Embodiment

Refer to Fig. 1, present embodiment discloses a kind of percutaneous passage stretching pliers, comprise two symmetrical configuration calipers, caliper comprises handle portion 1, articulated section 2 and working end 3; Handle portion 1 is positioned at the rear end of caliper, and the end of handle portion 1 is in the hollow and annular matched with human finger; Articulated section 2 is positioned at the middle part of caliper, and two calipers adopt pin hinged through articulated section 2; Working end 3 is positioned at the front end of caliper, and working end 3 is at right angles arranged relative to handle portion 1, and working end 3 is in the taper most advanced and sophisticated tapering, root is thick.As preferably, working end 3 length of described caliper is 3-10 centimetre.

In prior art, not special percutaneous passage expansion tool, medical personnel adopt vascular forceps instrument as an alternative usually.But the structure of vascular forceps is unfavorable for the operation that percutaneous passage is expanded, vascular forceps is generally the bending alive of straight shape, operator is caused to need to raise hand to adapt to otch when carrying out percutaneous passage expansion, both added after operation easier, easy obstruct the view again, make operator be difficult to observe the situation of otch, time serious, even can cause extra damage to patient.

The working end 3 of percutaneous passage stretching pliers of the present utility model adopts right-angle design, and the tip of working end 3 is comparatively tapering, root is comparatively thick, conveniently enters otch.In the process of carrying out percutaneous passage expansion, the endermic otch in working end 3 thrusts, and working end 3 is vertically inserted in tissue (being generally subcutaneous tissue, subcutaneous fat, body wall Musclar layer etc.), and then operator's joystick portion 1 struts and expands.In this process, the hand of operator holds handle portion 1, and it is comfortable that wrist places nature, and process of expansion more easily manipulates, and greatly reduces the difficulty of clinical tasks.The hand of operator is positioned at the side of the expanding channel of patient simultaneously, the sight line of expanding channel can not be hindered, so situation in operator's channel lumens that can expand from passway top view easily, distinguish the internal organs in muscle, tissue and deep, monitor process of expansion, improve the performance accuracy of percutaneous passage expansion, also greatly reduce the additional injuries to patient simultaneously.

A kind of percutaneous passage stretching pliers provided by the utility model, its working end 3 is at right angles arranged, and the hand carrying out operator during percutaneous passage expansion does not need unsettled lifting, and more convenient operation is comfortable.And the hand of operator can not block the sight line of access incisions, handled easily person observe, and improves the precision of operation, thus the damage to patient when also reducing clinical tasks further.

The above embodiment only have expressed a kind of embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
