Description
Technical field
This utility model relates to technical field of medical instruments, mainly for focus after carrying out intraperitoneal, peritoneum under the CT guiding, carries out the auxiliary puncturing kit of aspiration biopsy, radio frequency, microwave, radioiodine particle implanted treatment.
Background technology
The tumor common site after intraperitoneal, peritoneum, as: cancer of pancreas, renal carcinoma, abdominal cavity constitutional, metastatic tumo(u)r, retroperitoneal lymph node metastases etc.need carry out aspiration biopsy under the normal guiding of adopting CT or the image documentation equipment such as ultrasonic in clinical, clear and definite pathological diagnosis, or the radio frequency that punctures, microwave, radioiodine particle implanted treatment, but intraperitoneal, pathological changes after peritoneum, the human dissection position is dark, often be subject to stomach, intestinal, pancreas, the internal organs such as kidney, postcava, ventral aorta, splenic artery, spinal columns etc. hold, directly adopt fine needle aspiration biopsy, radio frequency, the treatments such as radioiodine particle implantation, easily damage surrounding organ, blood vessel etc., cause gastrointestinal damage to cause perforation, blood vessel injury causes massive hemorrhage etc., jeopardize patient's life.How to avoid above-mentioned vital tissue, internal organs, safely with puncture biopsy needle,, the insertion lesions positions such as microwave melt needle, radio frequency ablation needle, particle implant needle are successful surgery, the key that reduces postoperative complication.
Summary of the invention
This utility model will solve the existing puncture focuses such as puncture needle, radio frequency needle that directly adopt and easily cause the shortcoming of surrounding tissue, visceral organ injury, a kind of comparatively safe puncturing kit that focus puncture after intraperitoneal, peritoneum, radio-frequency (RF) ablation, radioactivity I125 particle are implanted is provided, satisfies the equipment that focus after intraperitoneal, peritoneum is carried out intervention diagnosis and therapy.
this utility model solves the technical scheme that its technical problem adopts: this abdominal cavity, peritoneum caudacoria pathological changes intervention diagnosis and therapy puncturing kit, comprise working column, puncture needle and ballhead push rod, working column is by the left-to-right fixed handle that comprises successively, trocar sheath and inner sleeve, wherein the both ends of the surface of fixed handle and trocar sheath are fixed together, be connected to the inner sleeve of telescopic action on the inwall of trocar sheath, the scale sign is all arranged on internal and external casing, wherein be provided with vertically the perforation puncture biopsy needle in working column, radio frequency ablation needle, the working column passage of radioiodine particle implant needle etc., wherein an end of puncture needle is the end that thrusts of needle-like, wherein the end that thrusts of puncture needle passes from the head of inner sleeve, wherein an end of ballhead push rod is provided with ball, wherein the head of inner sleeve is duckbill.After working column is sent into the abdominal cavity, withdraw from puncture needle, after the ballhead push rod is sent into working column, make duckbill inner sleeve head end become hemispherical, advance ballhead push rod and working column at intraperitoneal, make duckbill inner sleeve head end smoothly near pathological changes after abdominal cavity or peritoneum.
Wherein, the length of puncture needle is greater than the length of working column, and puncture needle is tapered from left to right.Puncture needle can be fixed together and be formed by one group of pipe fitting from coarse to fine, is convenient to puncture needle and enters the abdominal cavity with the working column stomach wall that jointly punctures.
Wherein, the afterbody of ballhead push rod is provided with limited block.The effect of limited block is the distance that restriction ballhead push rod slips into, and makes the ballhead of its front end just in time be positioned at the front end of working column.
in operation process, at first determine the position of focus under CT, reserve point of puncture, direction, the degree of depth etc., adopt puncture needle and working column, after common puncture enters the abdominal cavity, withdraw from puncture needle, with ballhead push rod and working column, adjust direction and the degree of depth, make duckbill inner sleeve head end smoothly near after pathological changes after abdominal cavity or peritoneum, withdraw from the ballhead push rod, send into puncture biopsy needle through working column, radio frequency ablation needle, radioiodine particle implant needle etc., carry out intervention diagnosis and therapy, for avoiding the interference such as working column radiofrequency ablation treatment, after radio frequency needle enters pathological tissues, inner sleeve is retreated in trocar sheath.
The effect that this utility model is useful is: this utility model is novel in design, simple in structure, easy and simple to handle, and safety is good, can effectively avoid accidentally injuring stomach, intestinal, close on internal organs and the tissue such as blood vessel, effectively improves simultaneously the puncture accuracy.
