Abstract

The utility model provides a chest wall pierce type labyrinth card which comprises a needle head, a guide wire, a needle core and a core tube, wherein the guide wire can penetrate through the needle head or the needle core, and the core tube is sleeved outside the needle core. According to the chest wall pierce type labyrinth card, a thinking of cutting and opening on the chest on the basis of the prior art is changed, the needle head is pierced into the skin of the chest firstly, then opening is conducted in a mode of needle core reaming, and therefore, the opening mode resolves the problem of slow recovery due to the cutting of the skin and the muscle tissue. After a surgery is conducted by the chest wall pierce type labyrinth card, the reaming position of the chest of patients can be self-contraction and forms a small opening hole, thus the chest wall pierce type labyrinth card is beneficial for recovery of wound of the patients.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the bent an outpost of the tax office of the thoracic wall puncture type that the utility model proposes is described in further detail.According to the following describes and claims, advantage of the present utility model and feature will be clearer.It should be noted that accompanying drawing all adopts very the form of simplifying and all uses non-accurately ratio, only in order to convenient, the purpose of aid illustration this utility model embodiment lucidly.

Core concept of the present utility model is, provide a kind of thoracic wall puncture type bent an outpost of the tax office, the bent an outpost of the tax office of described thoracic wall puncture type comprises syringe needle, seal wire, nook closing member and core cylinder, described seal wire can pass from described syringe needle or described nook closing member, described core jacket casing is outside described nook closing member, the bent an outpost of the tax office of the thoracic wall puncture type that this utility model provides has changed the thinking in thoracic cavity cutting perforate on the basis of existing technology, but first syringe needle is lunged in the skin at place, thoracic cavity, adopt again the mode of nook closing member reaming to come perforate, the mode of this perforate has been avoided owing to skin and muscular tissue being cut slowly problem of the recovery that brings, after the bent an outpost of the tax office of the thoracic wall puncture type that provides with this utility model has carried out operation, reaming place on the patient thoracic cavity can be shunk voluntarily, form a little perforate, be conducive to the recovery of patient's wound.

This utility model provides a kind of thoracic wall puncture type bent an outpost of the tax office, the bent an outpost of the tax office of described thoracic wall puncture type comprises syringe needle 1, seal wire 2, nook closing member 3 and core cylinder 4, described syringe needle 1 is axially arranged with the through hole that passes through for seal wire 2 in the edge respectively separately with described nook closing member 3, the external diameter of the internal diameter of described core cylinder 4 and described nook closing member 3 is complementary, and an end of described nook closing member 3 is provided with external diameter along the nook closing member head 31 that axially diminishes gradually from inside to outside of nook closing member 3.

The bent an outpost of the tax office of the thoracic wall puncture type that this utility model provides has changed the thinking in thoracic cavity cutting perforate on the basis of existing technology, but first syringe needle 1 is lunged in the skin 5 at place, thoracic cavity, adopt again the mode of nook closing member 3 reamings to come perforate, the mode of this perforate has been avoided owing to skin 5 and muscular tissue being cut slowly problem of the recovery that brings, after the bent an outpost of the tax office of the thoracic wall puncture type that provides with this utility model has carried out operation, reaming place on the patient thoracic cavity can be shunk voluntarily, form a little perforate, be conducive to the recovery of patient's wound.

Further, the nook closing member head 31 of described nook closing member 3 be shaped as taper shape, described nook closing member head 31 is that conical nook closing member 3 can be by the gradually wide design of its diameter, expand at an easy rate the aperture that syringe needle 1 is opened, core cylinder 4 can be entered from the hole that expands, and be subject to the deflation of skin and be fixed in the skin 5.

Can expect that the shape of an end of operation nook closing member 3 is so long as diameter wide shape gradually, the task of all can be competent at perforate.

Further, the diameter range of choice of described core cylinder 4 is 0.8-1.2cm, its diameter is preferably 0.8cm, and the core cylinder 4 of 0.8cm diameter is enough to make the instrument that carries out thoracic surgery to enter in patient's the thoracic cavity, causes skin 5 and muscular tissue to be subject to more macrolesion and need not that aperture is diffused into excessive diameter.

Describe the overall process of the bent an outpost of the tax office of this thoracic wall puncture type thoracic cavity perforate in detail below in conjunction with Fig. 1 to Fig. 4.

The first step of thoracic cavity perforate is that the syringe needle 1 with the bent an outpost of the tax office of this thoracic wall puncture type thrusts in the skin 5 at place, patient thoracic cavity, and seal wire 2 is penetrated from syringe needle 1 to skin 5;

The second step of thoracic cavity perforate is to extract syringe needle 1, syringe needle 1 is extracted out at an extrathoracic end from seal wire 2, core cylinder 4 is placed in outside the nook closing member 3, and seal wire 2 penetrated in the nook closing member 3 conical nook closing member heads 31 at an extrathoracic end, then nook closing member 3 and core cylinder 4 are moved to skin 5 places along seal wire 2, gradually nook closing member 3 is pressed in the skin 5, carries out reaming work, until the nook closing member head 31 of core cylinder 4 enters in the skin 5 fully;

The 3rd step of thoracic cavity perforate is after reaming is complete, extracts seal wire 2 and nook closing member 3, stays core cylinder 4 and struts perforate on the skin 5, and the doctor sees through perforate and uses operation tool to perform the operation.

Obviously, those skilled in the art can carry out various changes and distortion to this utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of this utility model claim and equivalent technologies thereof, then this utility model also is intended to comprise these changes and modification interior.
