Abstract
The utility model discloses a fixer for puncture under the guide of CT (computer tomoscanning). The fixer comprises a top plate, a main frame and a fixing clamp, wherein the main frame is an embedded type telescopic structure consisting of at least two sections, the bottom of the main frame is connected with the fixing clamp, and the top of the main frame is connected with the top plate; a clamp position for preventing the sections from swinging or separating from each other in the stretching and retracting process is arranged between the sections, and positions capable of being used for adjusting and fixing adjacent sections with smaller bores are arranged on the sections. The utility model has simple structure, is convenient to manufacture, avoids disinfection before operation and has no influence on puncture for sterile operation. A purpose for effectively fixing a biopsy gun can be achieved, risks occurring for the movement of the biopsy gun during operation are avoided, and the safety is improved. The fixer is simple to operate and can be operated by one person. The work efficiency is improved, and meanwhile, the bed rest time of a patient is shortened.
Description
Technical field
This utility model belongs to medical instruments field, and particularly a kind of CT guiding is the holder of puncture down.
Background technology
Along with popularizing of CT machine, the clinical practice of percutaneous transthoracic needle biopsy or interventional therapy more and more widely under the CT guiding.Very crucial in the piercing process to fixing of aspiration biopsy pin, especially the puncture needle of cell taking gun that tail end is heavier or connection ablating electrode is behind the human body raking, lack effective fixing means and equipment, cause easily position deviation occurring in the CT reseting procedure, press close to the puncture procedure of big airways or trunk even fatal complication can occur.Therefore, provide the safety that the puncture holder will improve piercing process greatly under a kind of simply and effectively CT guiding.
Summary of the invention
The shortcoming that the purpose of this utility model is to overcome prior art provides a kind of CT guiding simple in structure, easy to use, safe holder of puncture down with not enough.
The purpose of this utility model is achieved through the following technical solutions: a kind of CT guiding is the holder of puncture down, comprises top board, body frame and fixation clamp; Body frame is the nested type Collapsible structure that at least two sections are formed, and the bottom of body frame is connected with fixation clamp, and the top of body frame is connected with top board.
Be provided with screens between the described sections, avoid body frame in drawing process, to rock between the sections or break away from.
Described sections can be hollow cylindrical or hollow cylindrical.
The number of described sections is preferably 3 joints.
Described sections also is provided with the screw thread mouth that is used for fixing the sections position, and screw is regulated by screw thread mouth and fixed the next-door neighbour, is nested in the position of the sections in it.
Described fixation clamp is preferably groove structure, and the groove mouth is provided for the fixedly screw of body frame position away from body frame on the groove limit.
This utility model has following advantage and effect with respect to prior art:
(1) this utility model is simple in structure, easy to make, need not to sterilize before the art, does not influence sterile working's process of puncture.
(2) this utility model can reach the effectively fixedly purpose of cell taking gun, and the displacement of avoiding occurring cell taking gun in the art causes danger, has improved safety.
(3) this utility model is simple to operate, can the one man operation, reduce patient's bed rest time when increasing work efficiency.
Description of drawings
Fig. 1 is this utility model CT guiding front view of the holder of puncture down.
Fig. 2 is the CT guiding shown in Figure 1 right view of the holder of puncture down.
Fig. 3 is the CT guiding shown in Figure 1 stretching profile of the holder of puncture down.
Fig. 4 is the CT guiding shown in Figure 1 contraction profile of the holder of puncture down.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing this utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
A kind of CT guiding is the holder of puncture down, shown in Fig. 1～4: comprise top board, body frame and fixation clamp.
Body frame comprises 3 sections, the bore of the bore＜sections 3 of the bore＜sections 2 of sections 1, thus body frame forms nested type extension type structure.Be respectively arranged with screens 7 between the sections, avoid in drawing process, taking place the situation that sections rocks or breaks away from.The upper side of sections 2 designs screw thread mouth respectively, can be by the position of screw 8 adjustings and fixed-segment 1; The upper side of sections 3 designs screw thread mouth respectively, can be by the position of screw 9 adjustings and fixed-segment 2.
The top of sections 1 (being the body frame top) is connected with the top board 6 that is used to place puncture needle or puncture rifle.The bottom of sections 3 (being the body frame bottom) is connected with fixation clamp 4.Fixation clamp 4 is a groove structure, and the groove mouth is provided for fixing the screw 5 of body frame position away from body frame on the trough rim of groove.
The patient gets clinostatism, and capable routinely CT scan is determined the target focus and selected best inserting needle aspect on the CT display screen.Stick the metal grizzly bar at body surface, determine skin entry point, depth of needle and angle.
Holder (as shown in Figure 4) the CT of contraction state guiding is punctured down screws screw 5 fixation clamp 4 is installed in CT lathe edge, and the position of body frame is the plane, the corresponding skin entry point place of middle position of the top board 6 of sections 1 top connection.
Routine disinfection, skin penetrating Dian Pu hole towel are equipped with disinfecting towel in addition and cover holder.The local anesthesia of skin penetrating point row.
After puncture needle enters by the set angle and the degree of depth, hand-held another portable top board 6 that rises of pin, after the arrival ideal height, screw 8 and 9 are tightened.Biopsy needle can be fixed on the top board 6.Further sweeping CT again confirms to puncture or interventional procedure behind the position.
The foregoing description is this utility model preferred implementation; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under spirit of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
