Abstract

The invention relates to the field of medical equipment, particularly to a visible subcutaneous tissue dissector. The dissector comprises a tubular main body which is used for placing an endoscope, a duckbill head and a handle, wherein the duckbill head is arranged at the front end of the tubular main body, and the handle is sleeved with the tail part of the tubular main body; the handle is cylindrical, a first passage penetrating in the length direction of the handle is arranged at the inner part of the handle, the diameter of the lower half part of the first passage is the same as that of the outer wall of the tubular main body, and the diameter of the upper half part of the first passage is smaller than that of the lower half, so that a stepped structure is formed in the middle of the first passage to enable the lower half of the handle to be sleeved with the tail part of the tubular main body; a fixing piece for fixing the endoscope is arranged at the upper end of the handle, and a second passage communicated with the first passage of the handle is formed in the fixing piece. The dissector has the advantages of accuracy in stripping level positioning, no damage to the neighboring stripping level, and high operation effect.

Description

Visual subcutaneous tissue detacher

Technical field

The present invention relates to medical instruments field, be in particular a kind of visual subcutaneous tissue detacher.

Background technology

Be out at present in section's field of surgery, still do not exist a kind of being specifically designed to peel off the apparatus of specifying cortex, existing way is to rely on doctor's clinical experience to adopt common peeling off rod or peel off shears and carry out strip operation, but traditional like this way will exist following defect:

1, because the subcutaneous tissue thickness between individuality differs, if only peel off and often cannot accurately peel off in predetermined cortex with personal experience's judgement of doctor;

2, in the situation that not having image frame auxiliary, easily occur peeling off rod or peel off shears and depart from objectives to peel off level and enter into the adjacent level of peeling off and cause and close on the damage of peeling off level, thereby cause hemorrhage;

3, the operation technique that doctor by virtue of experience carries out, the long efficiency that causes performing the operation of operating time is not high conventionally.

Summary of the invention

The object of the invention is to: provide a kind of and peel off level accurate positioning, do not damage to close on and peel off level, the high visual subcutaneous tissue detacher of one of operation efficiency.

The present invention is achieved through the following technical solutions: the present invention includes tubular body, duckbilled head, hands handle for deploying endoscope; Described duckbilled head is located at the front end of tubular body, and taper knob is located at the afterbody of tubular body;

Described handle is cylindrical, handle inside is with the first passage connecting along decreased food direction, the first passage of lower semisection equates with tubular body outer diameter, thereby the diameter of first passage upper semisection is less than the diameter of lower semisection makes the lower semisection of handle can be set in the afterbody of tubular body at the medium position formation step structure of first passage, the upper end of handle is provided with the fixture for fixed endoscope, the inner second channel communicating with the first passage of handle that exists of fixture.

Compared with technology before, beneficial effect of the present invention is:

1, under Endoscope-assisted, doctor accurately localizing objects peel off level, damage little, save operating time.

2, duckbilled head with make coordinating of endoscope operation carry out in the middle of the present invention be not easy to depart from objectives cortex make near cortex be not damaged;

3, the present invention is more applicable to the operation technique peeled off of cortex and has the auxiliary of endoscope than common scalpel, and the efficiency of the operation making is higher.

Label declaration: 1-tubular body, 2-duckbilled head, 3-handle, 4-endoscope, 5-rubber ring, 6-shell, 7-depressed part, 8-buckle, 9-draw-in groove, 10-caulking gum film.

Detailed description of the invention

Below in conjunction with brief description of the drawings, the present invention is elaborated:

As shown in Figure 1, the present invention includes tubular body 1, duckbilled head 2, the handle 3 for deploying endoscope 4; Described duckbilled head 2 is located at the front end of tubular body 1, and handle 3 is set in the afterbody of tubular body 1;

As shown in Figure 3 and Figure 4, described handle 3 is cylindrical, handle 3 inside are with the first passage connecting along handle 3 length directions, the first passage of lower semisection equates with tubular body 1 outer diameter, thereby the diameter of first passage upper semisection is less than the diameter of lower semisection makes the lower semisection of handle 3 can be set in the afterbody of tubular body 1 at the medium position formation step structure of first passage, the upper end of handle 3 is provided with the fixture for fixed endoscope 4, the inner second channel communicating with the first passage of handle 3 that exists of fixture.

Fixture, handle 3 and tubular body 1 three's inner passage is interconnected and makes endoscope 4 to extend into duckbilled head 2 via passage from the tail end of fixture always.

Further, described duckbilled head 2 is transparent material, make when operation endoscope 4 can photograph constantly the image frame of duckbilled head 2 outsides.

Further, as shown in Figures 3 and 4, described fixture comprises shell 6, rubber ring 5 and caulking gum film 10;

Rubber ring 5 is that upper end open, lower end connect the columnar structured of caulking gum film 10, columnar structured inside and outside sidewall and upper surface are wrapped up by shell 6, the outer wall of described shell 6 bottoms is provided with buckle 8, and the inwall of handle 3 afterbodys is provided with the draw-in groove 9 coordinating with buckle 8.

When use, endoscope 4 punctures caulking gum film 10 and extend into the tube chamber inside of tubular body 1, caulking gum film 10 edges, cut place are close to the outer wall of endoscope 4 and are relied on caulking gum film 10 and endoscope 4 frictional force between the two to play the effect of fixed endoscope 4, therefore can be applicable to the endoscope 4 of various different models and all can reach good sealing and fixation simultaneously because the size of thorn cut depends on the caliber of endoscope 4.

Its operation principle is as follows:

When operation, endoscope 4 extend in the tube chamber of tubular body 1 via the passage of the fixture inside of afterbody and adjust the distance of endoscope's 4 photographic head and duckbilled head 2, and endoscope 4 is connected on outside display, under display image frame auxiliary, insert art target cortex in one's hands position, thereby duckbilled head 2 reaches and peels off the object of formulating cortex under the guiding of image frame constantly through the crack of adjacent cortex.
