Description

A kind of Ren sus domestica pedicle clamp

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly relates to a boar kidney pedicle clamp。

Background technology

In body in kidney medical operating, once find focus, it is necessary to carry out Operations Research and treatment, and in the process of Operations Research and treatment, it is necessary to by the pipeline of turnover kidney and kidney base of a fruit Guan Bi。It is generally required to use kidney pedicle clamp in this program, although prior art has had fairly perfect people's kidney pedicle clamp, but inventor finds in kidney surgery process that bigger its kidney base of a fruit of pig of head is bigger than people pig is carried out, if the kidney pedicle clamp still making employment can compare painstakingly, additionally for the less pig of head, it can be suitable for again people's kidney pedicle clamp, in order to reduce cost, convenient use, inventor thinks and designs what a kind of kidney pedicle clamp that can adjust clamping force was a need for。

Kidney pedicle clamp amplifies clamping force mainly by lever principle, if by lengthening clamp handle length, its clamping force also can increase。

Utility model content

Because the drawbacks described above of prior art, technical problem to be solved in the utility model is to provide a kind of Ren sus domestica pedicle clamp, and its clamp handle can stretch to adjust clamping force。

For achieving the above object, this utility model provides a kind of Ren sus domestica pedicle clamp, and including the first clamp handle and the second clamp handle, the first described clamp handle and the second clamp handle are mutually inserted, are assembled into one, at least provided with two card tieholens in the second described clamp handle；

The cross section of the first described clamp handle and the second clamp handle assembled portion is provided with cavity and two clamps, is provided with groove between two clamps；

The second described clamp handle and the first clamp handle assembled portion cross section are provided with Slipper and connecting plate, are connected by coupling part between described Slipper and connecting plate；Described Slipper and cavity assembling, described coupling part and groove assembling；

Being additionally provided with mounting groove on described Slipper, be provided with spring leaf in described mounting groove, described spring leaf adopts highly elastic material to make；

Described spring leaf is provided with clamping projection, and the first clamp handle and the second clamp handle are fixed together by described clamping protruding cooperation with the card tieholen being arranged on the first clamp handle side。

Further, the width of described connecting plate more than the width of coupling part, between connecting plate and Slipper, connecting portion office formed slot。

Further, described slot coordinates with clamp。

Further, described spring leaf adopts spring steel plate to make。

Further, described clamping is protruding is arranged to cambered surface with cavity wall contact surface。

Further, described cavity inner wall and clamping raised contact surfaces are provided with arcuate groove, and described arcuate groove contacts cooperation with cambered surface。

Further, the coefficient of friction of described arcuate groove and cambered surface contact portion can not more than 0.2。

Preferably, described clamping projection adopts smooth metal material to make。

The beneficial effects of the utility model are: this utility model is achieved that the adjustment of Kidney pedicle forceps clamp force by structure simply, and cheap and convenient use, adjustable additionally, due to its clamping force, adaptability is also greater than kidney pedicle clamp of the prior art。

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail:

Referring to Fig. 1 to Fig. 5, a kind of Ren sus domestica pedicle clamp, including the first clamp handle 1 and the second clamp handle 2, the first described clamp handle 1 and the second clamp handle 2 are mutually inserted, are assembled into one, at least provided with two card tieholens 13 in the second described clamp handle 2；

Referring to Fig. 2, the first described clamp handle 1 and the cross section of the second clamp handle 2 assembled portion are provided with cavity 12 and two clamps 11, are provided with groove 14 between two clamps 11；

The second described clamp handle 2 and the first clamp handle 1 assembled portion cross section are provided with slide block 22 and connecting plate 21, are connected by coupling part 25 between described Slipper 22 and connecting plate 21；Described Slipper 22 assembles with cavity 12, described coupling part 25 is assembled with groove 14, described connecting plate 25 width more preferably greater than the width of coupling part 25, so can between connecting plate 21 and Slipper 22, coupling part 25 place formed slot 24, described slot 24 coordinates with clamp 11, this structure can be effectively increased the stabilized soil pavement of the first clamp handle 1 and the second clamp handle 2 grafting part, it is prevented that during use, clamp handle is excessively loosening；

Being additionally provided with mounting groove 23 on described Slipper 22, be provided with spring leaf 3 in described mounting groove 23, described spring leaf 3 adopts highly elastic material to make, such as spring steel plate；

Described spring leaf 3 is provided with clamping projection 4, and described clamping projection 4 coordinates with the card tieholen 13 being arranged on the first clamp handle 1 side and the first clamp handle 1 and the second clamp handle 2 is fixed together；

During referring to Fig. 1 and Fig. 2 original state, described clamping protruding 4 coordinates fixing with the card tieholen 13 of low order end, when needs increase clamping force, have only to clamping projection 4 is pressed to the right (being as the criterion with Fig. 2), until clamping protruding 4 (is as the criterion with Fig. 1) to the right after departing from card tieholen 13 pulls the second clamp handle 2 until the card tieholen 13 of next card tieholen 13 or appropriate length coordinates clamping with clamping protruding 4 again；

Further, in order to reduce the abrasion of the clamping protruding 4 mill difference power with cavity 12 inwall and clamping projection 4 in pulling the second clamp handle 2 process, described clamping protruding 4 can be set to cambered surface 41 with cavity 2 sidewall contact face, and protruding 4 contact surfaces of described cavity 12 inwall and clamping can arrange arcuate groove 15, described arcuate groove 15 just contacts cooperation with cambered surface 41, this structure is except can reducing frictional force and abrasion, described arcuate groove 15 can also play the effect of guiding, it is prevented that in drawing process, clamping protruding 4 is sliding askew；

In order to reduce the frictional force of arcuate groove 15 and cambered surface 41 further, the coefficient of friction of described arcuate groove 15 and cambered surface 41 contact portion can not more than 0.2, and clamping protruding 4 adopts smooth metal material to make。

Preferred embodiment of the present utility model described in detail above。Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work。Therefore, all technical staff in the art pass through the available technical scheme of logical analysis, reasoning, or a limited experiment on the basis of existing technology according to design of the present utility model, all should in the protection domain being defined in the patent claims。
