Abstract

The invention discloses a tissue cutter and belongs to the field of medical equipment for surgeries. The tissue cutter comprises a cutter bar and a blade, wherein the cutter bar adopts a cavity structure with two opened ends, a clamping groove is formed in the top of the cutter bar, and the blade is fixed at the top of the cutter bar through the clamping groove; and the cutter bar is provided with scales, and the starting point of the scales is located at the top of the cutter bar. The tissue cutter is simple in structure and convenient to use; a cutting part can be positioned accurately by the aid of the cavity, a through hole and a guide wire; the depth of an incision can be accurately controlled through the scales; and in addition, blades with a series of sizes are set as a set of surgical instruments, and corresponding sizes can be selected for different surgeries, so that the operation of a minimally invasive surgery is greatly facilitated.

Description

Tissue dissection device

Technical field

The present invention relates to a kind of medical apparatus and instruments, relate in particular to a kind of tissue dissection device for Minimally Invasive Surgery.

Background technology

In Minimally Invasive Surgery, behind seal wire location, need to cut at seal wire vertical the tissues such as skin, the surgical knife using is at present used inconvenient, particularly deep tissues under skin is cut to difficulty, cause size incision not control, if otch is excessive, damage is just large, has also just lost Minimally Invasive Surgery meaning; If otch is too small, just can not cut deep tissues under skin, rigid insertion operating theater instruments, can cause torn tissue, healing difficulty.

Summary of the invention

For solving above-mentioned defect of the prior art, the invention provides tissue dissection device, solved operation inconvenience, the uncontrollable problem of size incision.

For solving the problems of the technologies described above, the present invention program comprises: tissue dissection device, it is characterized in that,

Comprise knife bar and blade, the cavity body structure that described knife bar is both ends open, the top of described knife bar is provided with draw-in groove, and described blade is fixed on knife bar top by draw-in groove; Described knife bar is provided with scale, and scale starting point is positioned at the top of knife bar.

Further, described blade comprises left blade and right blade, between described left and right blade, by connecting plate, connects, and described connecting plate is fixed in draw-in groove.

Further, the bottom of described knife bar is provided with handle, and in handle, is provided with connection cavity and extraneous through hole.

The invention has the beneficial effects as follows: the present invention is simple in structure, easy to use, by cavity, through hole and seal wire, can realize and operate on the accurate location at position, utilize scale, can the degree of depth of otch be realized accurately and being controlled, in addition, a series of blade size are set as a set of operating theater instruments, can be for different surgical selection corresponding size, greatly facilitate the carrying out of Minimally Invasive Surgery.

In figure: 1 knife bar, 11 cavitys, 12 draw-in grooves, 2 blades, 21 left blades, 22 right blades, 23 connecting plates, 3 handles, 31 through holes.

The specific embodiment

Below in conjunction with accompanying drawing, specific embodiment of the invention is described, should be appreciated that exemplifying embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, tissue dissection device comprises knife bar 1, blade 2 and handle 3, the cavity body structure that described knife bar 1 is both ends open, and the top of described knife bar 1 is provided with draw-in groove 12, described knife bar 1 is provided with scale, and scale starting point is positioned at the top of knife bar 1; Described blade 2 comprises left blade 21 and right blade 23, between described left and right blade, by connecting plate 23, connects, and described connecting plate 23 is fixed in draw-in groove 12; Described handle 3 is by screw thread or be fixedly connected on the bottom of knife bar 1, and in handle 3, is provided with and is communicated with cavity 11 and extraneous through hole 31.

Effect in order to guarantee to use, described handle 3 is yi word pattern, and vertical with knife bar 1, is convenient to grip.

Situation about using according to reality, can be a set of by the tissue dissection device composition of different size blade, is convenient to for difference operation, because the wound size of operating on depends on the widest part that left and right blade forms, therefore using this as standards of measurement.

In addition, the widest part that left and right blade forms is also depended in 0 position of the scale described in described left and right blade.

Before use, the sufferer position of operating at needs is in advance buried seal wire underground, chooses the tissue dissection device of suitable dimension, and seal wire is passed from cavity 11 and through hole 31, makes cutter accurately to arrive at sufferer place along seal wire.

During use, hold handle 3, along seal wire, adjusted blade to the direction of desired incision skin, observed graduation mark to blade and arrive after desired depth, extracted tissue dissection device, completed incision operation.

Should be understood that; the above-mentioned description for preferred embodiment is comparatively detailed; can not therefore think the restriction to scope of patent protection of the present invention; those of ordinary skill in the art is under enlightenment of the present invention; do not departing from the scope situation that the claims in the present invention protect; can also make the various deformation such as replacement, simple combination, within these all fall into protection scope of the present invention, the scope of asking for protection of the present invention should be as the criterion with claims.
