Abstract
The utility model relates to the technical field of medical appliances, in particular to a subretinal fluid drainage apparatus, which comprises a positioning tube, a drainage needle and a push rod. The subretinal fluid drainage apparatus is characterized in that the front end of the positioning tube is provided with a positioning opening and a drainage opening, a sliding groove is disposed on the side surface of the positioning tube, the drainage needle and the push rod are both located in the positioning tube, wherein the drainage needle is fixed at the front end of the push rod, the push rod is provided with a push handle, the push handle extends out of the positioning tube via the sliding groove on the side surface of the positioning tube, the positioning tube is provided with scale marks, and during usage of the subretinal fluid drainage apparatus, the positioning opening at the front end of the positioning tube is used for positioning a subretinal fluid portion at first, and then the push handle on the side surface of the positioning tube is pushed to lead the push rod in the positioning tube to push the drainage needle to extent out of the drainage opening so as to drain fluid of the subretinal fluid portion. In addition, the subretinal fluid drainage apparatus simplifies subretinal fluid drainage operation steps, reduces work intensity of medical staff and sufferings of patients, and has the obvious advantages of reasonable structure, convenient use, accurate positioning and the like.
Description
Technical field
This utility model relates to technical field of medical instruments, relates to a kind of retina tapping device specifically.
Background technology
As everyone knows, doing ophthalmologic operation especially in the surgery of retinal detachment process, because hydrops under the nethike embrane, can influence the carrying out of operation, this is often to need hydrops under the nethike embrane is bled off a part.The way of existing tapping technology is at first using localizer is surveyed needs tapping under the nethike embrane approximate location, use the tapping pin to carry out tapping then in this zone, complicated operation and locate inaccurate, both increased medical personnel's working strength, therefore increase the weight of patient's misery again, needed a kind of retina tapping device of rational in infrastructure, easy to use, accurate positioning.
Summary of the invention
This utility model is at the deficiencies in the prior art, proposes a kind of retina tapping device of rational in infrastructure, easy to use, accurate positioning.
A kind of retina tapping device, comprise positioning pipe, tapping pin, push rod, it is characterized in that the positioning pipe front end is provided with positioning port, tap hole, the positioning pipe side is provided with sliding recess, tapping pin and push rod all are positioned at positioning pipe, wherein the tapping pin is fixed on the push rod front end, and push rod is provided with and pushes away handle, pushes away handle and stretches out positioning pipe through the lateral sliding recess of positioning pipe.
This utility model can be provided with graduation mark on positioning pipe, be used for the length that accurate measurement tapping pin stretches out positioning port, prevents that tapping pin extension elongation is long, the patient harm eyeball.
This utility model in use at first uses the positioning port of positioning pipe front end that retina hydrops position is positioned, promote the lateral handle that pushes away of positioning pipe then, make the push rod in the positioning pipe promote the tapping pin to front slide, and stretch out tap hole, the hydrops place is carried out tapping, user can accurately be controlled the extension elongation of tapping pin by the graduation mark on the positioning pipe, prevent that tapping pin extension elongation is long, the patient harm eyeball, this utility model has been simplified the step of retina hydrops tapping operation, alleviated medical personnel's working strength and patient's misery, and had rational in infrastructure, easy to use, significant advantage such as accurate positioning.
Description of drawings:
Below in conjunction with accompanying drawing this utility model is described further.
Fig. 1 is a structural representation of the present utility model.
Reference numeral: positioning pipe 1, tapping pin 2, push rod 3, positioning port 4, tap hole 5, push away handle 6.
The specific embodiment:
A kind of retina tapping device, comprise positioning pipe 1, tapping pin 2, push rod 3, it is characterized in that positioning pipe 1 front end is provided with positioning port 4, tap hole 5, positioning pipe 1 side is provided with sliding recess, tapping pin 2 and push rod 3 all are positioned at positioning pipe 1, wherein tapping pin 2 is fixed on push rod 3 front ends, and push rod 3 is provided with and pushes away handle 6, pushes away handle 6 and stretches out positioning pipe 1 through positioning pipe 1 lateral sliding recess.
This utility model can be provided with graduation mark on positioning pipe 1, be used for the length that accurate measurement tapping pin 2 stretches out positioning port 4, prevents that tapping pin 2 extension elongations are long, the patient harm eyeball.
This utility model in use at first uses 4 pairs of retina hydrops of positioning port position of positioning pipe 1 front end to position, promote the positioning pipe 1 lateral handle 6 that pushes away then, make the push rod 3 in the positioning pipe 1 promote tapping pin 2 to front slide, and stretch out tap hole 5, the hydrops place is carried out tapping, user can accurately be controlled the extension elongation of tapping pin 2 by the graduation mark on the positioning pipe 1, prevent that tapping pin 2 extension elongations are long, the patient harm eyeball, this utility model has been simplified the step of retina hydrops tapping operation, alleviated medical personnel's working strength and patient's misery, and had rational in infrastructure, easy to use, significant advantage such as accurate positioning.
