Description
Technical field
This utility model belongs to medical instruments field, especially a kind of puncture needle support.
Background technology
At present, CT guiding percutaneous puncture interventional therapy down belongs to non-blood vessel intervention category, its applied range, and because of it has safety, effectively, wound is little, and advantages such as accurate positioning have become one of important means in clinical diagnosis and the treatment field.Puncture needle direction location will carry out after the shallow table position in patient's body that CT scan is examined the puncture needle direction, whether angle is correct by sticking a needle into when adopting this ruling by law to treat.It is more little that puncture needle enters in patient's body the shallow more support force that it is subjected to, and the operation doctor unclamps the easy run-off the straight of needle body behind the hands, and its angle changes, and causes CT scan to show that puncture needle angle and practical operation depart from, thereby influences the accuracy that inserting needle is operated.Conventional now solution is after the puncture needle run-off the straight, and the doctor suspends instruments adjustment puncture needles such as scanning and employing pliers and gets back to original angle, opens scanning device more again and operates.The mode of this artificial adjustment expends time in long, poor stability often needs to adjust repeatedly in a therapeutic process, causes the therapeutic process time lengthening, has increased patient's misery.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of puncture needle support is provided, this supporting structure is simple, design science is reasonable, easy to use, save time, can the firm support puncture needle, accurate positioning, effectively shorten the patient time.
This utility model solves its technical problem and is achieved through the following technical solutions:
A kind of puncture needle support comprises vertical support bar, rotary apparatus and horizontal support bar, and horizontal support bar connects vertical support bar by rotary apparatus, and an end of its horizontal support bar connects a puncture needle chuck by a rotary sleeve.
And described puncture needle chuck comprises fixation clamp and rotating clamp, and fixation clamp outer wall and rotary sleeve install, and rotating clamp one end is hinged by bearing pin and fixation clamp one end.
And described rotary sleeve is connected with horizontal support bar one end by lock-screw.
And, described rotary apparatus comprises the horizontal support bar positioning sleeve, lock shaft, the locking folder, lock sleeve and swingle, be shaped on locking hole on the horizontal support bar positioning sleeve, lock shaft is sleeved on the horizontal support bar positioning sleeve successively, in locking folder and the lock sleeve, lock shaft one end outer wall and lock sleeve inwall are connected with a joggle, the lock shaft other end is shaped on the mating holes corresponding with locking hole, horizontal support bar one end passes locking hole and mating holes is connected with rotary apparatus, swingle is installed on the lock sleeve, is arranged on locking folder and vertically supporting rod clamp stressed joint between lock sleeve and the horizontal support bar positioning sleeve.
And described vertical support bar lower end installs a slideway.
Advantage of the present utility model and beneficial effect are:
1, one end of the horizontal support bar of this puncture needle support connects a puncture needle chuck by a rotary sleeve, and rotary apparatus comprises the horizontal support bar positioning sleeve, lock shaft, the locking folder, lock sleeve and swingle, be shaped on locking hole on the horizontal support bar positioning sleeve, lock shaft is sleeved on the horizontal support bar positioning sleeve successively, in locking folder and the lock sleeve, lock shaft one end outer wall and lock sleeve inwall are connected with a joggle, the lock shaft other end is shaped on the mating holes corresponding with locking hole, horizontal support bar one end passes locking hole and mating holes is connected with rotary apparatus, swingle is installed on the lock sleeve, be arranged on locking folder and vertically supporting rod clamp stressed joint between lock sleeve and the horizontal support bar positioning sleeve, this kind structure can be in therapeutic process the supplemental support puncture needle, make puncture needle angle and fixed-site, remain on required inserting needle trend, thereby obtain accurate data.
2, the puncture needle chuck of this puncture needle support comprises fixation clamp and rotating clamp, and fixation clamp outer wall and rotary sleeve install, and rotating clamp one end is hinged by bearing pin and fixation clamp one end, this is simple in structure, easy to adjust, time saving and energy saving, effectively saved the puncture needle operating time.
3, the vertical support bar lower end of this puncture needle support installs a slideway, and this slideway can be connected with the CT bed, and the convenient position of adjusting whole puncture needle support is to adapt to different orientation needs.
4, this utility model is simple in structure, design science is reasonable, easy to use, save time, can the firm support puncture needle, accurate positioning, effectively shorten the patient time, be a kind of safe and reliable puncture needle support.
