Abstract
The utility model relates to the technical field of medical appliances, in particular to a sleeve for creating a micro-channel to protect internal pressure. The sleeve comprises a sleeve body, wherein the sleeve body is of a cylindrical structure, one end of the sleeve body is provided with a connecting part, the sleeve body and the connecting part are both hollow, the sleeve body is communicated with the connecting part, the sleeve body and the connecting part are of an integrated structure, and one end of the sleeve body is provided with a sleeve valve. According to the utility model, through the arrangement of the sleeve and the sleeve valve, when the sleeve penetrates into the eye through the puncture knife, the puncture knife is pulled out, the sleeve is separated from the puncture knife, the sleeve is left on the eye, and meanwhile, the sleeve valve blocks the through hole of the sleeve, so that the pressure in the eye is ensured, the damage and the wound quantity of the instrument repeatedly entering the eye to the intraocular tissue in the ophthalmic operation are reduced, the operation difficulty of doctors is reduced, the pain of patients is relieved, the operation treatment can be completed through a very small wound, and the patients can recover quickly.
Description
Technical Field
The utility model belongs to the technical field of medical appliances, and particularly relates to a sleeve for creating a micro-channel to protect internal pressure.
Background
With the progress of the development of the science and technology, the concept of "minimally invasive" has been advanced into various fields of surgical operations, such as microsurgery, which is widely used in ophthalmic surgery. Minimally invasive surgery has the advantages of small trauma, light pain and quick recovery. The minimally invasive surgery reduces the harm of the traditional surgery to the human body, and greatly reduces the inconvenience and pain of patients given by diseases. For example, microsurgical instruments are used in eye surgery to remove tissue from a delicate and limited space within the human body, and the created micro-tunnels can protect other tissues within the eye from damaging other tissues during surgery, and the created tunnels can reduce the damage to the tissues by repeated entry of the instruments into the eye by the intraoperative instruments.
During the ophthalmic surgery, the instruments in the ophthalmic surgery need to repeatedly enter the eyes, so that the surgical instruments are easy to repeatedly damage the tissues in the eyes in the entering process, the number of wounds is increased, the operation difficulty of doctors is improved, the pain of patients is aggravated, and the recovery of the patients is slower.
Disclosure of utility model
In view of the above, the present utility model provides a cannula that creates a micro-channel that protects the internal pressure. Including the sleeve pipe, the sleeve pipe is cylindric structure, sheathed tube one end is provided with connecting portion, be hollow setting in sleeve pipe and the connecting portion, sleeve pipe and connecting portion are linked together, just sleeve pipe and connecting portion are integrated into one piece structure, the sleeve pipe valve is installed to sheathed tube one end, the sleeve pipe valve is installed on the connecting portion, the sleeve pipe valve is linked together with connecting portion and sleeve pipe.
The beneficial effects of the utility model are as follows:
According to the utility model, through the arrangement of the sleeve and the sleeve valve, when the sleeve penetrates into the eye through the puncture knife, the puncture knife is pulled out, the sleeve is separated from the puncture knife, the sleeve is left on the eye, and meanwhile, the sleeve valve blocks the through hole of the sleeve, so that the pressure in the eye is ensured, the damage and the wound quantity of the instrument repeatedly entering the eye to the intraocular tissue in the ophthalmic operation are reduced, the operation difficulty of doctors is reduced, the pain of patients is relieved, the operation treatment can be completed through a very small wound, and the patients can recover quickly.
Additional features and advantages of the utility model will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model. The objectives and other advantages of the utility model may be realized and attained by the structure particularly pointed out in the written description and drawings.
Drawings
In order to more clearly illustrate the embodiments of the present utility model or the technical solutions of the prior art, the following description will briefly explain the drawings used in the embodiments or the description of the prior art, and it is obvious that the drawings in the following description are some embodiments of the present utility model, and other drawings can be obtained according to these drawings without inventive effort for a person skilled in the art.
FIG. 1 shows a schematic diagram of a structure according to an embodiment of the present utility model;
Fig. 2 shows a schematic diagram of an explosive structure according to an embodiment of the utility model.
In the figure: 110. a sleeve; 130. a first connection portion; 210. a sleeve valve.
Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-2, the present utility model provides a technical solution: a cannula that creates a micro-channel that protects the internal pressure. Including sleeve pipe 110, sleeve pipe 110 is cylindric structure, the one end of sleeve pipe 110 is provided with connecting portion 130, be hollow setting in sleeve pipe 110 and the connecting portion 130, sleeve pipe 110 and connecting portion 130 are linked together, just sleeve pipe 110 and connecting portion 130 are integrated into one piece structure, sleeve pipe valve 210 is installed to the one end of sleeve pipe 110, sleeve pipe valve 210 installs on connecting portion 130, sleeve pipe valve 210 is linked together with connecting portion 130 and sleeve pipe 110.
The inside of sleeve 110, connecting portion 130 and sleeve valve 210 communicates, cooperates the puncture sword simultaneously and uses, and the puncture sword passes sleeve 110, connecting portion 130 and sleeve valve 210's inside, then when the puncture sword pierces inside the eye, pulls out the puncture sword, sleeve 110 and puncture sword separation, sleeve 110 stay on the eye, and sleeve valve 210 blocks up sleeve 110's through-hole simultaneously, guarantees inside pressure of eye.
The connection 130 is used to mount the sleeve 110 on the sleeve valve 210, and to mount the sleeve 110 and the sleeve valve 210.
Although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
