Description

A kind of incision protective sleeve of anti-operation smoke

Technical field

The utility model is related to medical instruments fields, and in particular to a kind of incision protective sleeve of anti-operation smoke.

Background technology

In surgery open surgery, doctor usually requires auxiliary implement and is led to the soft tissue or bone of operative incision It opens to expose the operative site visual field.For a long time, this surgery assistor tool largely used is generally metal retractors and draws Hook, and metal drag hook has the shortcomings that pulling force is uneven, limited view, thus there is the application of incision protective sleeve.Due to cutting Mouth protective case uniform force, damage of the medical instrument to skin when can protect surgical procedure, while the use of incision protective sleeve The horizontal elongation degree of notch can be reduced, post-operative recovery is convenient for.

Incision protective sleeve is widely used in because that can expose good surgical field of view in open surgery.However in hand During art, the use of various electric knifes will bring a large amount of operation smoke, and the delay of operation smoke will seriously affect hand The art visual field, traditional mode drawn in such a way that external drainage pipe draws smog it is intraperitoneal must not operation smoke, and it is external Drainage tube will influence the normal operating of surgical instrument, and be repeatedly inserted into and extract the very big drop that external drainage tube causes operation It is low, and existing incision protective sleeve is difficult to control the operation smoke that surgical procedure generates；It is oozed simultaneously because cutting part will appear Blood will flow to operative site when oozing of blood is excessive and cause the visual field fuzzy, doctor is needed to take other measures to eliminate Surgery The blood stains of position, this certainly will will lead to the delay of operation, increase the operation risk of patient.

Utility model content

The utility model to solve the above-mentioned problems, devises a kind of incision protective sleeve of anti-operation smoke, the protective case The operation smoke generated during notch intra-operative is not only can control, can also prevent the blood stains of cutting part from flowing to Surgery Position provides good surgical field of view for being normally carried out for surgery open surgery, improves the efficiency of operation.

In order to achieve the above technical purposes, reach above-mentioned technique effect, the utility model is real by the following technical programs Existing：

A kind of incision protective sleeve of anti-operation smoke, including upper snap ring, operation path and lower snap ring, it is characterised in that：On The side of snap ring is equipped with negative port, and operation path is made of inner layer pipe and outer layer pipe, and several drainages are provided on lower snap ring Hole, the upper snap ring are solid circle, and lower snap ring is hollow ring, and inner layer pipe and outer layer pipe are individually fixed in snap ring Inside and outside lower snap ring, drainage tube is embedded between inner layer pipe and outer layer pipe, drainage tube one end connects with negative port It connects, the other end of drainage tube and the cavity perforation of lower snap ring connect.

Preferably, the negative port is horizontally placed on the outside of snap ring, and conduction hole is set to the lower section of lower snap ring Outside.

Preferably, the upper snap ring and lower snap ring are made of polyurethane material, the inner layer pipe, outer layer pipe It is made of silica gel material with drainage tube.

The utility model has the beneficial effects that：The protective case not only can control the operation generated during notch intra-operative Smog can also prevent the blood stains of cutting part from flowing to operative site, be provided well for being normally carried out for surgery open surgery Surgical field of view, improve the efficiency of operation.

Description of the drawings

In order to illustrate more clearly of the technical solution of the utility model embodiment, make required for being described below to embodiment Attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description is only some embodiments of the utility model, For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings Other attached drawings.

Fig. 1 is the surface structure schematic diagram of the incision protective sleeve of anti-operation smoke；

Fig. 2 is the perspective structure schematic diagram of the incision protective sleeve of anti-operation smoke；

Fig. 3 is the Section A-A sectional view of the incision protective sleeve of anti-operation smoke.

In attached drawing, parts list represented by the reference numerals are as follows：

The upper snap rings of 1-, 2- operation paths, snap ring under 3-, 4- drainage tubes, 21- outer layer pipes, 22- inner layer pipes, 31- drainages Hole, 41- negative ports.

Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts The all other embodiment obtained, shall fall within the protection scope of the present invention.

Refering to fig. 1 shown in -3, a kind of incision protective sleeve of anti-operation smoke, including upper snap ring 1, operation path 2 and lower card Ring 3, the side of upper snap ring 1 are equipped with negative port 41, and negative port 41 is horizontally placed on the outside of snap ring 1, operation path 2 by Inner layer pipe 22 and outer layer pipe 21 form, and are provided with several conduction holes 31 on lower snap ring 3, conduction hole 31 is set to lower snap ring 3 Lower outer, the upper snap ring 1 are solid circle, and lower snap ring 3 is hollow ring, and inner layer pipe 22 and outer layer pipe 21 are distinguished It is fixed on inside and outside snap ring 1 and lower snap ring 3, drainage tube 4 is embedded between inner layer pipe 22 and outer layer pipe 21, drain 4 one end of pipe is connect with negative port 41, and the other end of drainage tube 4 and the cavity perforation of lower snap ring 3 connect.

When using the present apparatus, by lower snap ring 3 in the tissue wall inside operative incision merging notch, upper snap ring 1, which is stuck in, to be cut On mouth superficies, slot side by stretching and maintains size incision under the tension force effect of operation path 2；Operative process Oozing of blood is excessively and under the flow direction of 2 outer surface of operation path when snap ring 3 on middle generation operation smoke or notch wall, by negative port 41 are connected to negative pressure suction device or are directly connect with negative port using syringe, and the operation smoke in notch is inhaled in negative pressure It is extracted under drawing from the cavity that the conduction hole 31 of 3 lower outer of lower snap ring enters to inside lower snap ring 3 and along drainage tube 4, and The blood stains that notch wall stretches out can also be extracted from drainage tube 4, to prevent operation smoke or blood stains from flowing to operative site and shadow Ring surgical field of view.
