Embodiment Construction
[0012] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0013] Such as figure 1 and figure 2 As shown, in this embodiment, a needle adjustment device for planting needles is composed of a needle tail sleeve 1, a connecting rod 2 and a handle 3, and the connecting rod 2 connects the needle tail sleeve 1 with the handle 3 , the needle tail sleeve 1 of the insertion needle is made of metal, the length of the sleeve is 5 mm, the inner diameter is 3 mm, and the thickness of the sleeve tube wall is 3 mm. There is a ring with a ring at 1 / 2 of the inner wall of the sleeve, which can be connected with the insertion The groove of the needle tail is in close contact to prevent the needle from coming out of the cannula.
[0014] The length of the connecting rod 2 is 20mm, and the length of the handle 3 is 50mm.
[0015] The handle 3 is made of plastic or rubber, and the handle 3 and the connecting rod 2 are integ...

Abstract
The invention discloses a needle adjusting device for inserting and implanting needles, and belongs to the field of medical apparatuses and instruments. The invention aims to provide the needle adjusting device, which is convenient for clinicians to adjust the depth of an implanting needle during implanting treatment operation, the needle adjusting device is composed of an implanting needle tail sleeve, a connecting rod and a handle, the implanting needle tail sleeve is connected with the handle through the connecting rod, the implanting needle tail sleeve is made of a metal material, a circle of snap spring is arranged at the 1 / 2 position of the inner wall of the sleeve, and can be in close contact with a groove in the tail of the implanting needle, and the implanting needle is prevented from being disengaged from the sleeve. An operator holds the handle by hand, inserts the implantation needle tail into the implantation needle tail sleeve, enables the clamping spring in the inner wall of the sleeve to clamp the implantation needle tail groove, and then pushes the implantation needle into an affected part to complete needle adjusting operation.
Description
technical field [0001] The invention relates to a medical device, in particular to a needle adjustment device for implanting needles, which is convenient for operators to adjust the depth of interpolation needles. Background technique [0002] Interstitial implantation technique is a brachytherapy technique that directly inserts interstitial needles into the tumor body in a certain order for treatment. It is suitable for patients whose anatomical site allows or needs to maintain organ function. Located on the body surface and near the body surface. It can treat cervical cancer, prostate cancer, tongue cancer, oral cancer and so on. At present, the number of units that carry out inter-tissue interplantation at home and abroad is gradually increasing, and the technical difficulty of interplantation lies in the distribution of the implantation needles and the adjustment of the depth of the interpolation needles. The implantation technology is becoming more and more mature and...
