Description
Technical field
This utility model belongs to animal tissue's field of planting, particularly relates to a kind of experiment tumor puncture and plants pin.
Background technology
Often need set up animal tumor model in medical animal experiment process, tumor tissue's local planting method is common method.Existing method mainly relies on the operating theater instruments such as tweezers piece of tissue to be inserted need plant position, has following shortcoming: 1. for the tumor planting of internal organs, often need perform the operation, and implanted by tumor block after exposing internal organs, wound is large; 2. because piece of tissue is smooth, usually not easily clamp in actual mechanical process, not easily inserts, and inserts rear piece of tissue and easily skid off with tweezers.
Summary of the invention
For the problems referred to above, main purpose of the present utility model is solve tumor tissue in traditional zoopery to plant the technical problem wasted time and energy, and to reduce laboratory animal wound, the experiment tumor puncture improving plantation success rate plants pin.
For achieving the above object, this utility model adopts following technical scheme: experiment tumor puncture plants pin, it is characterized in that: comprise the needle guard of hollow, the solid nook closing member that can insert in needle guard; Described needle guard comprises thrusting and thrusts portion in animal body, is arranged at the afterbody in the portion of thrusting, for containing portion that is hand-held and splendid attire tumor tissue; Described nook closing member comprises and can slide in the portion of thrusting and tumor tissue be sent forward in needle guard the push rod pushed in animal body, be arranged on push rod afterbody and with containing portion with the use of pushing block; The length of described push rod is equal to or greater than the length in the portion of thrusting.Push rod is generally equal with the length of thrusting portion, and Qia Shi tumor tissue releases the portion of thrusting and enters in the tissue of animal body.By arranging containing portion, be convenient to people's hand operated, tumor tissue can be placed in one pushes simultaneously again, convenient.
Preferably, the portion of thrusting described in is hollow cylindrical; Described push rod is the cylindric push rod be used in conjunction with each other with the portion of thrusting of hollow cylindrical.By arrange columned with the use of structure, make that push rod is easier to slide in the portion of thrusting.
Preferably, described pushing block is provided with graspable handle.By arranging handle, more convenient operation.
Preferably, the top in portion is thrust described in for ease of thrusting needle point in animal body, the pointed shape in inclined-plane.By arranging needle point, more easily the portion of thrusting is thrust in animal body, and reduce the injury to animal body.
Described thrust portion is provided with can show the scale that length in animal body is thrust in the portion of thrusting.By arranging scale, the portion of thrusting can be demonstrated and thrust length in animal bodies, avoiding causing damage to animal body.
Described needle guard and nook closing member are that rustless steel is made.More durable in use.
This utility model adopts puncture needle for relying on, and carries out the fixing of tumor tissue and pushes.
Experiment tumor puncture plantation pin is metal structure, visible under the iconographys such as ultrasonic, radiation, can carry out iconography guiding; Front end is the pointed pin in inclined-plane, can the soft tissue such as prick skin, muscle easily, piece of tissue is sent to and need plant position, realize Wicresoft's plantation, without the need to operation.
Nook closing member first retreats when using with tumor puncture plantation pin by experiment; tumor tissue is inserted in needle guard; due to outer field protection; piece of tissue can firmly be fixed in needle guard; be placed in desirable behind plantation position until experiment tumor puncture plantation pin needle point; push away before nook closing member; tumor tissue in needle guard can be pushed to needle point position by push rod; pin is planted because now piece of tissue departs from experiment tumor puncture completely; therefore now exit experiment tumor puncture and plant pin; piece of tissue, by being firmly positioned at plantation position, can not skid off.
Compared with prior art:
1. only need an experiment tumor puncture to plant pin, intervention puncture can be carried out under image-guided, make the tumor planting at some position not need operation to carry out.
2. tumor tissue is easily fixed, and easily plants, not easily slippage, improves plantation success rate.
This utility model convenient operation, reduces the wound to laboratory animal, improves and is modeled as power, solves the problem that tumor block planting method in zoopery process is time-consuming, require great effort.

Detailed description of the invention
Below in conjunction with detailed description of the invention, utility model content of the present utility model is described in further detail.Should understand, embodiment of the present utility model is unrestricted this utility model for illustration of this utility model only, when not departing from this utility model technological thought, according to ordinary skill knowledge and customary means, the various replacement made and change, all should be included in scope of the present utility model.
As shown in Figure 1, Figure 2, Figure 3 shows, experiment tumor puncture plants pin, it is characterized in that: comprise the needle guard of hollow, the solid nook closing member that can insert in needle guard; Described needle guard comprises the portion of thrusting 1 can thrust in animal body, is arranged at the afterbody in the portion of thrusting 1, for the hand-held and containing portion 2 of splendid attire tumor tissue 8; Described nook closing member comprises and can slide in the portion of thrusting 1 and tumor tissue 8 be sent forward in needle guard the push rod 3 pushed in animal body, be arranged on push rod 3 afterbody and with containing portion 2 with the use of pushing block 4; The length of described push rod 3 is equal to or greater than the length in the portion of thrusting 1.Described portion 1 of thrusting is for hollow cylindrical; Described push rod 3 is the cylindric push rod 3 be used in conjunction with each other with the portion of thrusting 1 of hollow cylindrical.Described pushing block 4 is provided with graspable handle 5.Described top of thrusting portion 1 is for ease of thrusting needle point 6 in animal body, acute angle.Described thrust portion 1 is provided with can show the scale 7 that length in animal body is thrust in the portion of thrusting 1.Described needle guard and nook closing member are that rustless steel is made.
As shown in Figure 3, during use, first needle guard is thrust in animal body, tumor tissue 8 is placed in containing portion 2; By hand-held handle 5, with push rod 3, tumor tissue 8 is pushed in the portion of thrusting 1, then pushed in animal body by the portion of thrusting 1.When the portion of thrusting 1 is identical with push rod 3 length, push rod 3 is completely overlapping with the portion of thrusting 1, tumor tissue 8 can be pushed in animal body.Finally extract needle guard out.
