Description

A kind of screw radiotherapy thermoplastic memory body film card punch

Technical field

This utility model relates to technical field of medical equipment, particularly relates to a kind of screw radiotherapy thermoplastic memory body film card punch.

Background technology

Medically, often use a kind of low temperature thermoplastic memory body film positioned in radiotherapy section office, for patient chest, abdominal part or the Postural immobilization at pelvic cavity position before radiotherapy.This body film has tabular or netted, plasticity is strong, put into and 60-70 DEG C of hot water gets final product fully transparent softening, moulding one-tenth can be stretched according to patient size and be suitable for the fixing mould of each patient, patient can be completely fixed after cooling, make patient arbitrarily can not move because of a variety of causes, thus meet radiotherapy precision and the needs of radiotherapy in the most whole course for the treatment of.Each patient's body film made needs to take off from a patient after cooling down completely, opens the square opening of three about 3 centimeters as requested, for patient body position's labelling on body film.

The method that perforate is commonly used is manually to pluck out square opening with cutter.But there is certain degree of hardness after the cooling of body film, operate with cutter very inconvenient, it is easy to hole burr occurs, and is easy to injure medical worker；It addition, because the body film made overarches according to build, make proper film uneven distribution in moulding process, during stingy hole, slightly firmly inequality will mark the longest seam on body film, is also scratched by hole exterior domain, makes a mess of body film；Also have and be exactly, the lowest by cutter efficiency, can not meet requirements of one's work.

Utility model content

In view of above-mentioned analysis, the purpose of this utility model is that a kind of screw radiotherapy thermoplastic memory body film card punch of offer, and this card punch can facilitate the punching of radiotherapy body film, improves work efficiency, the safety of protection medical worker.

The purpose of this utility model is mainly achieved through the following technical solutions: a kind of screw radiotherapy thermoplastic memory body film card punch, it is characterised in that: include screw rod, guide post, slide block, base, cutter head；Described screw rod bottom is crouched in the hugging being located at described base, described guide post and screw rod are fixed in described base abreast, described slide block thread bush is located in described screw rod, and the most smooth is set in described guide post, and described cutter head is arranged on the bottom of described slide block；Described cutter head has the square edge of a knife.

Further, described screw tip is with screw on nut.

Further, described cutter head includes that the knife back and blade, the described knife back are connected on described slide block, and described blade has four, and four limits along the described knife back surround the described square edge of a knife vertically downward, and the point of a knife on described blade is perpendicular to the knife back and flats down.

Further, described blade is triangle, or rectangle, or trapezoidal.

The most described point of a knife is unicuspid dihedral, or zigzag.

The beneficial effects of the utility model are as follows: 1. this utility model designs the body of a screw dexterously, can connect cutter head by arranging slide block on screw rod on slide block, it is achieved only rotary screw just can make that cutter head is the most descending pierces through body film.2. cutter head is square edge of a knife form, the most just cuts out a square opening.3, blade can be that triangular knife can also be for rectangle serrated knife, and cutting force is strong, due to sharpness and the formability feature of cutter head, so this utility model can be by the cut hole molding of hard plastic body film.

Other feature and advantage of the present utility model will illustrate in the following description, and, becoming apparent from description of part, or understand by implementing this utility model.

Accompanying drawing is only used for illustrating the purpose of specific embodiment, and is not considered as restriction of the present utility model, and in whole accompanying drawing, identical reference marks represents identical parts.

Fig. 1 is the overall structure sketch of this utility model card punch.

Fig. 2 is embodiment one structure diagram of card punch cutter head.

Detailed description of the invention

Specifically describing preferred embodiment of the present utility model below in conjunction with the accompanying drawings, wherein, accompanying drawing constitutes the application part, and is used for explaining principle of the present utility model together with embodiment of the present utility model.

As it is shown in figure 1, the screw card punch that this utility model provides mainly is made up of five parts, including screw rod 1, guide post 2, slide block 3, base 4, cutter head 5.

Screw rod 1 top is with screw on nut, and screw rod bottom is sleeping to be located in base 4, by switching screw on nut, screw rod 1 can be made to rotate in the hugging of base.Guide post 2 and screw rod 1 are fixed in base 4 abreast, and guide post 2 is immovable.Slide block 3 is set on screw rod 1 and guide post 2 simultaneously, and wherein with the connection of screw rod 1 for threadeding, the connection with guide post 2 is that unthreaded hole connects.When screw rod 1 and guide post 2 are vertically placed, slide block 3 is rendered as level；Cutter head 5 is installed in the bottom of slide block 3.

When donor film 6 punches, this device is placed in body film side, by the drilling point on cutter head 5 alignment body film, then rotary screw 1, now due to screw rod 1 bottom withstand in base 4 can not feeding, and slide block 3 had both been threadeded with screw rod 1 and had been smoothly connected with guide post 2, and guide post 2 is parallel to each other with screw rod 1, so slide block 3 can be descending along screw rod 1 straight line, band dynamic cutter head 5 moves closer to body film 6, until punching body film.

Cutter head 5 can be by bolt or rivet interlacement to slide block 3 bottom, it is also possible to be welded to slider bottom.In this utility model, cutter head 5, as the critical component of directly punching, has its structural particularity, as in Figure 2-4, in order to get square opening on body film, cutter head 5 is designed as in this utility model square edge of a knife form.Cutter head 5 includes the knife back 51 and blade 52, and the knife back 51 is a square flat part, is connected in slide block 3 base plane；Blade 52 has four, can form along the one bending of the four of the knife back 51 limit and the knife back, or be individually welded on four limits of the knife back can also, four blades 52 surround the square edge of a knife, and the point of a knife direction of blade 52 is perpendicular to the knife back and flats down.

Further, the form of blade 52 can have multiple, and as in Figure 2-4, blade 52 monnolithic case has triangle square or trapezoidal several, point of a knife is positioned at insert bottom, and point of a knife can have unicuspid dihedral, it is possibility to have zigzag, in a word, pointed point of a knife is sharper, can be with quick penetration body film 6.

Further, in order to accurately find the drilling point on body film, the method being preferably utilized on body film 6 drawing sphere of movements for the elephants lattice, the central point that the central point of sphere of movements for the elephants i.e. punches, the foothold of the housing of sphere of movements for the elephants that is four slice blade 52.

During work, first on the body film 6 moulded, mark drilling point (picture sphere of movements for the elephants) with marking pen, then body film is placed on a platform；Card punch is placed in body film side, owing to being empty inside body film, it is possible to put in inside body film by described base 4；Rotary screw 1, makes slide block 3 constantly decline, cutter head 5 infinite approach drilling point constantly centering, makes cutter head fast powerful ground penetrator film after continuing to decline.

The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.
